On the bright side, it’s user-friendly with six different settings, including sit up and massage modes. I found the sit up setting to be the most comfortable and effective for muscle contractions. The belt is adjustable and should fit most users thanks to its Velcro design. The battery life is impressive and lasts a long time before needing a recharge. However, I should mention that it can be quite painful at levels above 8, and you’ll need to push it to at least level 7 for effective contractions after the three-month mark. Just remember to keep the pads moist while using!

The effectiveness of this device blew me away. The electrical muscle stimulation technology works wonders, targeting the abs with incredible precision and delivering a profound workout. I could genuinely feel my muscles contracting and working hard, just like during an intense gym session.

Setting it up was effortless. The instructions were straightforward, and in just a few minutes, I was ready to begin my workout. The various intensity levels allowed me to customize the stimulation to suit my fitness level and objectives. Whether I wanted a light, massage-like experience or a more intense muscle-building session, the MarCoolTrip MZ ABS Stimulator delivered perfectly.

Comfort is another standout feature. The soft material and ergonomic design made it not only effective but also enjoyable to wear. I could easily put it on under my clothes without anyone noticing, seamlessly integrating it into my daily routine.

After using it consistently for a few weeks, I began to see visible results. My core felt stronger, and my abs appeared more defined. It complemented my regular exercise routine exceptionally well, providing an additional boost to my abdominal workouts.

Maintenance is also simple. The gel pads are durable and easy to replace, ensuring the stimulator remains effective over time.

In conclusion, I highly recommend the MarCoolTrip MZ ABS Stimulator to anyone wanting to enhance their abdominal workouts in a convenient and effective way. It’s a fantastic investment for anyone serious about fitness or looking to tone their abs with minimal effort.

After 5 months of ownership, my initial positive impressions (which you can read in my original review below) have turned into sheer frustration. Its performance has dramatically declined to the point of being nearly unusable.

I used this belt twice daily, 4-5 times a week, diligently wiping off sweat and charging it weekly. Everything was fine until about a week ago when the vibrations weakened significantly. I was accustomed to the 6th mode at strength level 15, but now it feels like level 5. Anything below strength 10 barely registers. It seems like the device lost its power overnight, with no changes to my routine. To clarify, this isn’t due to my increasing tolerance; the lower strength settings barely vibrate anymore, and this drastic change happened almost instantly.

To make matters worse, the company that sells this product is unresponsive. I had to go through Amazon to get in touch with them, as there’s no trace of them online or any contact information available. After several days without a response, I’m still left in the dark about whether this issue is covered by a warranty. For a $70 item, this situation is incredibly frustrating.

The only reason I’m giving this review two stars instead of one is that I genuinely liked it when it worked. It provided solid resistance for my abs, and I appreciated the routine it became part of. However, its current barely functional state and the seller’s lack of communication leave me deeply disappointed. I don’t believe $70 is a fair price for something that only lasts a few months.

ORIGINAL REVIEW
I’ve been using this device for a few weeks now, and I initially liked it. While it won’t give you a six-pack on its own, I’ve noticed a slight toning in my abs, thanks to combining it with a healthy diet and regular exercise. As a supplement to my fitness routine, it has helped me avoid abdominal exercises I dislike by mimicking the feel of crunches.

I wear it twice daily for 20 minutes each session, which is about all I can tolerate before the discomfort sets in. I started at level 4 and have worked my way up to level 10, primarily using the sixth mode. Each mode has a distinct feel, which I appreciate.

I recommend this product, but be aware that it’s not a miracle device. However, I do want to address a couple of significant issues:

First, the battery life is hard to gauge. At times I’ve had to charge it after a week, then after a day, and other times after a few days, despite consistent session lengths. When charging, a red LED light indicates it’s charging, but it would be helpful to have a low battery alert, maybe by flashing red when turned on.

My main concern is the absence of a kill switch. The three buttons include plus/minus for intensity and an M button for mode selection. The jump in intensity between levels can be significant. I experienced a painful cramp when switching from level 8 to 9 because there’s no immediate off button. I had to rapidly click the minus button while in discomfort. An off switch is crucial; it makes me hesitant to increase past level 10. The cramp felt like a kick to the side, and I can’t understand how they overlooked this critical feature.

Despite these issues, I’m still giving it four stars overall. It fits comfortably, provides a solid workout, is easy to clean and store, and offers a decent variety of options. Importantly, I’ve noticed a slight difference in my abs, even without changes to my workout or diet. After three weeks of use, I can’t complain too much!

EDIT: After consistent use for a few months, I find it durable, and the battery seems to last well, requiring charging only once a week. Regarding the lack of a kill switch, I’ve discovered a workaround: switching modes automatically resets the intensity to level one. I’ve reached level 15 on my preferred mode without cramping now. For a quick shut-off, I click the M button and then the minus button. It’s a bit clunky, and I still wish for a dedicated off button, so I’m keeping this review at four stars. However, it’s an improvement over my previous method of rapidly clicking the minus button to turn it off.

Overall, I’ve grown more positive about this machine over time. I believe it’s worth getting if you use it consistently. Lastly, it charges via micro-USB, which feels outdated; for the price, it should use USB-C.
