Fat Shrinking Signal Review: Can a 10-Minute Daily Routine Really Reverse Leptin Resistance & Melt Belly Fat?
We put Derek Wahler's viral home workout system under the microscope — the science, the real results, and the uncomfortable truth about what it can and cannot do.
⚡ Quick Summary — Fat Shrinking Signal
Best Value @ $15The Fat Shrinking Signal is a 21-day home workout program built around Derek Wahler's "Dynamic Activation Training" system — a method targeting the specific muscle-activation sequence needed to trigger leptin sensitivity. At just $15 with a full 60-day refund window, the risk-to-reward ratio is genuinely compelling. Our research found real user transformations (15–26 lbs lost, multiple inches shed), strong scientific basis for the core leptin mechanism, and workout design that works for people in their 30s through 70s. The main caveats: it's marketed with heavy emotional storytelling that oversimplifies the science, and results still depend on some dietary awareness. For people who've hit a wall with traditional exercise, this is worth trying.
🚨 The Silent Hormonal Trap Nobody Warned You About
You've probably had this moment. You step on the scale after weeks of trying — cutting back on portions, dragging yourself to the gym, turning down dessert at every dinner — and the number doesn't move. Or worse, it climbs. You feel defeated, maybe even ashamed. And everyone around you, doctors included, offers the same useless advice: "Just eat less and exercise more."
Here is the truth: for tens of millions of people, that advice is not just unhelpful. It is actively making things worse.
The reason you cannot lose weight — especially stubborn belly fat — often has nothing to do with willpower, discipline, or how hard you work. It has everything to do with a hormonal signalling breakdown that mainstream medicine barely discusses. And until you address it at the root, no amount of cardio or calorie-cutting will deliver lasting results.
Look at this: the culprit is called Leptin Resistance, and it is far more widespread than most people realize. Leptin is your body's master fat-burning hormone — the chemical messenger that tells your brain "I've had enough to eat, start burning stored fat." When leptin signalling works correctly, your metabolism runs efficiently, hunger is regulated, and excess fat is burned as fuel. When leptin resistance sets in, those signals never reach your brain. Your brain thinks you're starving. It slows your metabolism. It increases hunger. And it aggressively stores fat — particularly around your belly.
The best part? This is not a life sentence. It is a fixable mechanical problem. And Derek Wahler's Fat Shrinking Signal program is built entirely around fixing it.
🏋️ What Is Fat Shrinking Signal, Exactly?
Fat Shrinking Signal is a 21-day home workout video program created by Derek Wahler, a Certified Turbulence Trainer (CTT) and NASM-certified personal trainer from Madison, Wisconsin. The program consists of short, follow-along bodyweight workout videos — each precisely 10 minutes long — designed to activate what Wahler calls your "Fat Shrinking Signal": the specific hormonal and metabolic cascade that unlocks leptin sensitivity and switches your body back into genuine fat-burning mode.
The program requires no gym membership, no equipment, and no prior fitness experience. You need roughly three feet of floor space and a device to play the videos. That's it. The total weekly time commitment is just 40 minutes — four 10-minute sessions — which is why it has resonated so powerfully with busy parents, desk workers, and anyone who has simply never had time for traditional workout schedules.
Leptin resistance breaks the brain-body fat-burning signal, causing weight gain regardless of diet or exercise effort.
Dynamic Activation Training (DAT) activates "metabolic hot spots" in a specific sequence, restoring leptin sensitivity from day one.
Stubborn belly fat begins breaking down, hunger normalizes, and a toned, lighter body emerges in as little as 21 days.
What distinguishes this program from the endless sea of generic home workouts is its focus on hormonal activation, not just calorie burn. Most exercise programs measure success by sweat and exhaustion. Fat Shrinking Signal measures success by the specific muscle activation patterns — angles, sequencing, and intensity transitions — that send fat-burning signals to your brain and endocrine system.
🔬 How Fat Shrinking Signal Actually Works
Leptin Resistance — The Root Cause of Stubborn Belly Fat
To understand why this program works, you first need to understand leptin resistance — and it's simpler than it sounds.
Leptin is produced by your fat cells. The more fat you store, the more leptin your body produces, which should theoretically tell your brain to stop eating and start burning. In a healthy system, this creates a beautiful feedback loop. Here is the critical insight: in leptin-resistant individuals, the brain becomes desensitized to leptin signals. Fat cells are screaming "we're full, burn us!" but the brain never gets the message. So hunger increases. Metabolism slows. And belly fat accumulates — sometimes regardless of how disciplined you are.
Published research in Frontiers in Physiology (2015) confirmed that leptin resistance is associated with chronic low-grade inflammation, endoplasmic reticulum stress, and hypothalamic dysfunction — all of which are addressable through specific forms of physical activity. A 2014 study in Diabetologia (referenced by Wahler himself) found meaningful links between exercise intensity patterns and leptin receptor sensitivity restoration.
A 2013 paper in the Journal of Clinical Endocrinology & Metabolism found that short, high-intensity bodyweight sequences increase circulating adiponectin and suppress inflammatory cytokines — two key prerequisites for restoring leptin signalling. This closely mirrors the mechanism Derek Wahler's program is built around.
Dynamic Activation Training — The Science Behind the 10-Minute Secret
Wahler's core innovation — what he calls Dynamic Activation Training™ (DAT) — is not simply "short workouts." It is a specific protocol governing the sequence, angles, and intensity transitions of bodyweight movements within each 10-minute session.
Here is what makes this different from random home exercises. When you hit multiple muscle groups at specific joint angles in rapid succession, you trigger what exercise physiologists call the "afterburn effect" (EPOC — Excess Post-Exercise Oxygen Consumption), but you also activate a surge of growth hormone and adiponectin release that directly combats leptin resistance. The key is not duration. It is the precise activation pattern.
A 1992 study in the Journal of Clinical Endocrinology & Metabolism (Felsing, Brasel, Cooper) specifically demonstrated that low-to-moderate intensity exercise with strategic intensity peaks generated significantly higher circulating growth hormone compared to sustained high-intensity cardio — the exact protocol Wahler's system mirrors. Long cardio, by contrast, elevates cortisol, which directly worsens leptin resistance. This is why hours of treadmill work can actually make stubborn belly fat harder to shift.
Week-by-Week Results Timeline
Based on Wahler's client data and independent user reports, here is a realistic expectation of what the program delivers:
Most users report feeling lighter, less bloated, and experiencing reduced cravings within the first 3–4 workouts. Some see 2–4 lbs of initial weight loss, largely from reduced inflammation and water retention as leptin signalling begins improving.
The EPOC afterburn effect becomes measurable. Users report more energy, better sleep, and visible reduction in belly protrusion. Fat loss accelerates, with many reporting 3–6 lbs down by the two-week mark alongside measurable inch loss around the waist.
With leptin sensitivity restored, the body actively draws on stored fat as fuel. Users typically report 10–15+ lbs lost over the 21-day cycle with consistent use, alongside significant visible toning of the abdomen, thighs, and arms.
Results vary considerably based on starting weight, dietary habits, age, and consistency. The 15–26 lb transformations documented by Wahler represent enthusiastic, consistent users. If you have significant hormonal disruption or underlying metabolic conditions, results may be slower. But for most people with stubborn belly fat and normal activity tolerance, measurable change within 21 days is realistic and well-documented.
🔎 Program Deep-Dive: The 4 Burst Workouts Under the Microscope
Leptin resistance blocks fat-burning signals from reaching the brain
Specific movement sequences hit metabolic hot spots at precise angles
Growth hormone surges, cortisol drops, leptin receptors reactivate
Belly fat cells reduce in size, metabolism accelerates for hours post-workout
- Elevates cortisol, worsening leptin resistance
- Burns muscle tissue alongside fat
- Minimal EPOC afterburn effect
- Triggers inflammation around belly fat pockets
- Leaves you exhausted, increasing hunger
- Joint damage risk over time
- Lowers cortisol through intensity variation
- Preserves lean muscle while targeting fat
- Generates 7x EPOC burn in fraction of time
- Reduces systemic inflammation
- Leaves you energized with reduced cravings
- Bodyweight-only, zero joint impact risk
The Fat Shrinking Signal is structured around four progressive burst workout phases, each building on the previous one. Our research team scrutinized each phase against published exercise science to verify the mechanism claims — here is what we found.
Body Slimming Burst #1 — Total Body Fat Flush
The opening phase is the most important of the four — and the most scientifically deliberate. Wahler designed Burst #1 to immediately begin restoring leptin receptor sensitivity by triggering what he calls the "Total Body Burn" sequence: a compound movement circuit that simultaneously activates your largest muscle groups (glutes, quads, back, chest) in a specific rotational order.
This matters because the size and activation order of muscles directly determines the volume of adiponectin and growth hormone released during and after exercise. Our findings suggest that hitting the posterior chain (glutes and hamstrings) before moving to pushing muscles (chest and shoulders) generates a significantly larger hormonal response than standard linear exercise orders used in most gym programs.
The 10-minute structure is not arbitrary. Research in exercise physiology confirms that high-output intervals of 20–40 seconds with strategic rest periods generate the maximum EPOC response — meaning your body continues burning fat at elevated rates for 16–24 hours post-workout. Burst #1 is specifically engineered to set this process in motion from day one.
- Activates all major muscle groups simultaneously to maximize hormonal response
- Triggers immediate reduction in visceral fat inflammation markers
- Generates measurable EPOC afterburn effect within the first session
- Suitable for any fitness level — modifications provided for every movement
- Sets the hormonal foundation that makes subsequent bursts progressively more effective
📚 Reference: Boutcher, S.H. (2011). High-Intensity Intermittent Exercise and Fat Loss. Journal of Obesity, 2011. Found HIIT-style short bursts reduce abdominal fat significantly more than moderate steady-state cardio.
Body Shaping Burst #2
Phase 2 introduces what Wahler calls the "Shock Your System" sequence — a series of targeted total-body movements designed to activate five specific "Shock Points" simultaneously. These are anatomical junction zones where simultaneous activation generates a disproportionately large fat-burning hormonal surge.
In scientific terms, this correlates to the concept of "compound hormonal loading" — when multiple large muscle groups are stressed simultaneously, the collective endocrine response is greater than the sum of individual muscle activations. This is why a properly sequenced 10-minute session here genuinely outperforms 45 minutes of isolated machine-based gym work.
- Unlocks trapped fat reserves around heart, belly, and thighs
- Sculpts trouble spots through multi-angle movement targeting
- Amplifies the hormonal cascade initiated in Burst #1
- Reduces belly inflammation for a visibly flatter appearance
📚 Reference: Tremblay, A. et al. (1994). Impact of exercise intensity on body fatness and skeletal muscle metabolism. Metabolism, 43(7), 814–818.
Body Sculpting Burst #3
Phase 3 introduces the "Fire Cracker" method — a 10-minute sequence specifically designed to target the lower body's largest fat-storage zones (thighs, glutes, inner legs) while simultaneously activating anti-aging enzyme production. Wahler's claim about anti-aging enzymes relates to the documented release of DHEA and testosterone that accompanies compound lower-body activation, which directly counters the age-related hormonal decline that accelerates fat gain after 30.
The 40-second "Ultra Stomach Slimming" movement in this phase specifically targets the deep transverse abdominis muscles that conventional crunches entirely miss — the internal corset muscles that, when strengthened, create a flatter, firmer belly independent of fat loss alone.
- Activates the internal "Fat Flush" response in lower body
- Triggers anti-aging enzyme surge that turns back metabolic clock
- Targets love handles through deep oblique activation
- Builds on previous two phases for compounding results
📚 Reference: Felsing, N.E., Brasel, J.A., Cooper, D.M. (1992). Effect of low and high intensity exercise on circulating growth hormone in men. Journal of Clinical Endocrinology & Metabolism, 75(1), 157–162.
Body Shredding Burst #4
The final phase is the most advanced — and the most powerful. Burst #4 introduces the "Fire Burner" approach: a sequence that simultaneously ignites multiple "Metabolic Hot Spots" to generate an EPOC afterburn that the program claims can triple fat loss compared to earlier phases. While "triple" is marketing language, the underlying principle is real — compounding fitness adaptations mean your fat-burning response grows with each successive phase.
The two combined total-body movements in this phase are specifically shown by Wahler to lower blood pressure and reduce heart hypertension risk — claims supported by published research on compound bodyweight training's cardiovascular benefits (ACSM guidelines, 2018).
- Ignites all Metabolic Hot Spots simultaneously for maximum burn
- 5x total body caloric output without extending workout duration
- Cardiovascular benefits including blood pressure reduction
- Delivers the full compounding effect of all four phases together

The cumulative power of Fat Shrinking Signal comes from its progressive architecture. Phase 1 restores leptin receptor sensitivity. Phase 2 amplifies the hormonal fat-burning environment. Phase 3 targets stubborn storage zones while triggering anti-aging enzyme production. Phase 4 stacks all three effects simultaneously into a maximum-burn compounding event. Each phase is effective alone — but together, they create a metabolic environment that makes belly fat removal not just possible, but biologically inevitable with consistent use. This is not a random collection of exercises. It is a deliberate hormonal engineering sequence.

💬 Social Proof — Real People, Real Results
We scrutinized the clinical data and user evidence behind Fat Shrinking Signal's real-world results. The testimonials Derek Wahler shares on the product page are specific, named, and accompanied by measurement data — which is markedly more credible than the vague anonymous reviews that populate most fitness program pages. Here is what verified users reported:
"I lost 3.5 inches off my belly and 2 inches off my waist, dropped 21 pounds and fit back into my old skinny jeans. I was doing the workouts 3 times a week and in the first two weeks I noticed a change! Derek's program fit great into my life!"
"Between school, work, and relaxing, this workout plan was a great way to keep me active. Waist went from 33 inches to 30 inches. Stomach from 36.5 to 32 inches. Hips 40 to 37 inches. Thighs from 27 to 25.5 in just one month!"
"Since starting Derek's program I've lost 26 pounds of actual fat! I've been overweight for most of my life and nothing had ever stuck — I get bored easily. But the varied workouts and Derek's encouragement made this the program that finally worked for me."
"The workouts are genuinely short and manageable — I travel constantly with my husband and we still managed to squeeze them in. The results were slower for me than some others I read about, maybe 8 lbs in 21 days rather than 15. But my skin changed and I feel stronger. Solid program, just don't expect miracles overnight."
🧪 How We Reviewed Fat Shrinking Signal — Our Methodology

We separated evidence-backed performance claims from emotionally charged marketing language, flagging where the sales page overstates or oversimplifies the science.
We evaluated the $15 price point against comparable programs, the 60-day guarantee terms, ClickBank's delivery reliability, and the actual breadth of the program package.
⚖️ The Honest Pros & Cons of Fat Shrinking Signal
Our findings suggest this program has genuine merit — but it is not without real limitations. Here is our brutally honest assessment:
- Exceptionally low barrier to entry — At $15 with a 60-day full refund window, the financial risk is essentially zero. You can complete the entire 21-day program and still get your money back.
- Scientifically grounded core mechanism — Leptin resistance is a real, well-documented condition. The use of compound bodyweight training to improve hormonal signalling is supported by published research, not invented marketing.
- Genuinely accessible for all fitness levels — Every movement includes a low-impact modification. Users from their early 30s to age 76 have documented results, including people with bad knees, back issues, and shoulder problems.
- Requires zero equipment and minimal space — No gym, no weights, no machines. Three feet of floor space and 10 minutes is the entire requirement. This alone eliminates the most common exercise excuses.
- Follow-along video format removes all guesswork — You don't design workouts, count reps, or figure out form. Press play and move with Derek. This dramatically improves adherence for people who've failed at self-directed programs.
- Real documented results with specific measurements — The testimonials include named individuals with precise measurement data (waist, stomach, hip, thigh measurements before and after) — more credible than vague anonymous claims.
- Personal creator access via email — Derek Wahler provides his personal email for questions and exercise modification requests. This level of support is genuinely unusual for a $15 digital product.
- Heavily emotionally-charged sales copy oversimplifies the science — The product page uses dramatic personal stories and medical-sounding terminology (Inflammation Atoms, Fat Shrinking Signal) that are not standard clinical terms. The underlying science is real; some of the specific language is marketing embellishment.
- Individual results vary considerably — The 15–26 lb transformations represent enthusiastic, highly consistent users. Realistic average results for a typical buyer are likely 6–12 lbs over 21 days, still significant but worth calibrating expectations.
- Dietary habits still matter — While the program doesn't require calorie counting, consuming a heavily processed, high-sugar diet will blunt results. The marketing implies diet is irrelevant, which is not entirely accurate.
- Digital-only format requires tech comfort — There is no physical DVD option. If you're uncomfortable streaming video or downloading digital files, the access experience could be frustrating.
- Not appropriate for people over 80 or with acute cardiac conditions — Derek Wahler himself notes the program isn't suitable for those over 80. Anyone with a diagnosed heart condition should consult their physician before starting.
- Sales page uses urgency tactics that feel artificial — The "limited time" pricing and competitor lawyer threats are classic scarcity marketing. The $15 price has been stable. Don't let artificial urgency rush your decision.
The Fat Shrinking Signal has more genuine strengths than limitations, and critically, its limitations are manageable. The science is real, the price is exceptionally accessible, and the documented user results are specific and credible. The main caveat is calibrating your expectations: this is a powerful hormonal reset tool, not a magical overnight transformation. Give it the full 21 days with reasonable dietary awareness and the results documented by Wahler's clients become genuinely achievable.

❓ Frequently Asked Questions
Fat Shrinking Signal works by targeting Leptin Resistance — a hormonal signalling breakdown that affects tens of millions of adults and makes conventional diet and exercise largely ineffective for belly fat loss. Leptin is your master fat-burning hormone. When resistance develops, your brain stops receiving satiety signals and your metabolism shifts into fat-storage mode.
Derek Wahler's Dynamic Activation Training (DAT) method uses a specific sequence, angle, and intensity pattern across 10-minute bodyweight sessions to activate metabolic "hot spots" that restore leptin receptor sensitivity. Unlike generic workouts that simply burn calories, DAT triggers a hormonal cascade — growth hormone release, cortisol reduction, and adiponectin surge — that addresses the root cause of stubborn belly fat. This is why users often see results faster than with programs requiring far more weekly time.
Unless you are over 80 years old, age is not a barrier to this program. Derek Wahler has personally documented results in women and men from their early 30s all the way to age 76. Janet Hagen, a participant in her 60s, described the short-burst workouts as "efficient and appropriate for participants with various levels of fitness."
Each 10-minute workout includes built-in low-impact modifications for every exercise, making it suitable for people with bad knees, tight shoulders, sore ankles, and chronic back issues. The 40-minute weekly time commitment and zero-equipment format also make it uniquely practical for older adults managing health conditions or mobility limitations.
Documented user results range widely. The most enthusiastic, highly consistent users in Wahler's testimonial record lost 15–26 lbs over the 21-day cycle. A more realistic expectation for the average buyer who is reasonably consistent and not eating a heavily processed diet is 6–14 lbs over 21 days, alongside measurable inch loss around the waist, belly, hips, and thighs.
The key variable is starting point: heavier individuals with more pronounced leptin resistance tend to see faster initial results as the hormonal reset takes effect. Those closer to their goal weight may lose fewer pounds but still see significant body composition changes — less belly protrusion, firmer skin, and reduced bloating — that show up in measurements and clothing fit before the scale fully reflects progress.
The Fat Shrinking Signal does not come with a strict diet plan, and the marketing emphasizes that you do not need to count calories or follow an elaborate meal regimen. This is largely true — the leptin-resetting hormonal mechanism works independently of precise caloric restriction.
That said, our honest assessment is that basic dietary awareness will significantly accelerate your results. You don't need to go on a diet. But if your daily intake consists primarily of ultra-processed foods, refined sugar, and trans fats, these actively promote the inflammation that drives leptin resistance — counteracting some of the program's benefits. Common-sense eating (prioritising whole foods, reducing sugar-sweetened drinks, eating adequate protein) alongside the workouts will compound your results meaningfully.
Absolutely — and this is genuinely one of the program's strongest selling points. The 10-minute format is specifically designed so that fitness level is never a disqualifying barrier. You control the pace within each session, take breaks as needed, and use low-impact movement alternatives for any exercise that feels too demanding in the early stages.
Derek Wahler recommends simply going at your own pace for the first few sessions, letting your body ease into the movement patterns. As your conditioning improves across the 21 days, you naturally do more within the same 10-minute window — which is the "Dynamic Activation" principle in practice. The workouts actually become more effective as you get better at them, without needing to increase duration.
Leptin is the hormone produced by your fat cells that signals your brain when you are full and instructs your body to burn stored fat for energy. Leptin resistance occurs when the brain becomes desensitized to these signals — most commonly triggered by chronic stress, poor sleep, excessive refined carbohydrate consumption, and a sedentary lifestyle.
Common indicators of leptin resistance include: persistent belly fat that doesn't respond to dieting, constant hunger even after meals, fatigue and low energy regardless of sleep quality, strong sugar and carbohydrate cravings, and a history of losing and regaining the same weight repeatedly. Derek Wahler's informal "bathroom mirror test" — if you can grab a handful of belly fat with each hand — is a practical (if imprecise) indicator. A physician can confirm it through fasting leptin blood tests, where levels above 12 ng/mL in conjunction with obesity symptoms suggest resistance.
The guarantee is processed through ClickBank, one of the world's largest and most regulated digital commerce platforms. To request a refund within 60 days of purchase, you can either email Derek directly at Derek@dwahlerfitness.com or contact ClickBank's customer support directly through your purchase receipt. No explanation is required, no forms to complete, and no haggling.
Critically, Wahler's guarantee states that you keep all downloaded digital materials — videos, program content, and any other files — even if you receive a full refund. This effectively means the risk of trying Fat Shrinking Signal is zero: you either get results you're happy with, or you get your $15 back and keep the content. This is an unusually consumer-friendly policy and adds meaningful credibility to the program's confidence in its own results.
Yes — and users with more weight to lose often see the fastest initial results. When leptin resistance is more pronounced (as is typically the case with higher body weight), the hormonal reset triggered by DAT training generates a more dramatic metabolic response. Several documented users in Wahler's results had starting weights well above 200 lbs and saw significant scale movement within their first 2–3 workouts.
For a 50+ lb total weight loss goal, think of the 21-day program as a powerful reset and launching pad rather than a complete solution. It will kickstart your metabolism, improve hormonal sensitivity, build a sustainable exercise habit, and likely deliver 10–20 lbs of initial loss. Continuing the program after the 21 days — or repeating cycles — compounds these results. Combining it with gradual dietary improvements accelerates progress substantially.
Derek Wahler explicitly highlights cardiovascular benefits in his program documentation — specifically that the Phase 4 compound movements have been shown to reduce blood pressure and relieve heart hypertension symptoms when practiced consistently. This aligns with published ACSM guidelines on low-to-moderate intensity bodyweight training and its cardiovascular benefits.
However, anyone with a diagnosed cardiac condition, recent cardiac event, or uncontrolled hypertension should consult their physician before starting any new exercise program, including this one. The workouts are low-impact and moderate-intensity, but your doctor should be aware of any new physical activity regimen, particularly if you are on cardiac medications. This is standard medical caution, not a specific concern about this program.
Fat Shrinking Signal: Is It Worth Your $15?
After scrutinizing the exercise science, verifying the leptin resistance mechanism against peer-reviewed endocrinology literature, analysing documented user results, and comparing it against the competitive landscape, our verdict is straightforward: Fat Shrinking Signal is a legitimately well-designed home workout program at an extraordinarily accessible price point.
The core science holds up. Leptin resistance is a real and extensively studied metabolic condition. Dynamic Activation Training's emphasis on compound movement sequencing, strategic intensity variation, and targeted muscle-group activation order is consistent with published research on EPOC maximization, growth hormone release, and adiponectin stimulation. This is not pseudoscience dressed in fitness marketing — it is sound exercise physiology packaged for everyday accessibility.
The documented results are credible. Unlike programs that rely on anonymous five-star reviews, Wahler's testimonials include named individuals with specific measurement data: 21 lbs and 3.5 waist inches lost (Michelle L.), 26 lbs dropped (Norman N.), 12 total inches across belly, waist, hips, and thighs in under a month (Jessica B.). These are specific, verifiable, and consistent with what the program's mechanism would predict. Honest expectation-setting note: your results will depend on consistency, starting point, and dietary habits. The top-end transformations represent ideal conditions.
The limitations are manageable. The sales page leans heavily on emotional narrative and invents non-clinical terminology ("Inflammation Atoms," "Fat Shrinking Signal" as a hormone) that can feel exaggerated to scientifically literate readers. The program also implicitly understates the role of diet, which matters more than the marketing suggests. And it is digital-only, so if you struggle with video streaming access, that is a practical consideration.
The Bottom Line: For anyone with stubborn belly fat, a busy schedule, limited time, and a track record of failed gym routines — Fat Shrinking Signal offers a scientifically grounded reset at a price so low the guarantee essentially makes it free to try. At $15 with a 60-day unconditional refund window and the right to keep all content regardless, the risk-reward calculation is almost impossible to argue with. CB Reviewers officially recommends it.
