  • Awesome product
i’m not going to bash this product because it’s a good one — I’d even give it 5 stars. But it’s not good for me personally because it triggers anxiety and epileptic episodes for me. I feel awful that I am unable to use it — so I will be returning it.

  • Stopped working after a month
When I first got this belt, I absolutely loved it! It worked so well. I was using it consistently for about a month and saw results in that short time. My stomach was definitely more toned and the product was so easy to use. I would just wear it every night for about 30 minutes before bed, so this item could not be easier to incorporate into your day-to-day life and use consistently. I wore the belt at the highest level on almost every setting. There is some discomfort (I guess you could say) from the shocks that are sent to your abdomen but it’s nothing too crazy. You definitely feel your muscles squeezing and relaxing with every shock. Anyways, I absolutely love the product but I’m past my return/refund date and I don’t think this item has a warranty -which totally sucks!! I would like to get a replacement but I don’t wanna pay for it again because it’s kind of ridiculous that it broke after a month… this kind of item should come with a year warranty. Honestly, I think I got a faulty product because it seemed like it was a quality item, but my battery thing stopped charging so the belt is totally useless to me now. Reached out to Amazon customer service to have the issue resolved by buy at your own risk I guess! ... show more

  • It works (strengthens core), love the side pads, but I hope for more sizes and durability
Ordered a replacement but still ended up returning it due to quality issues. Maybe I am just unlucky. I really liked the item, which is why I hope the manufacturers will read this review and make some improvements, so I can buy it in the near future. Honest feedback here: Pros: - it works, which is what I bought it for. I do feel like my core is stronger, and it burned some abdominal fat - easy to use - side pads is definitely a unique feature, and I love it - some EMS products shock too intensely that users seemed to be in pain. This product never caused such problems for me. Shock intensities are tolerable and effective, in my opinion Cons: - my first one stopped working properly after a few uses, and the replacement was straight-up defective. For something that costs ~$80, I am expecting it to last for at least two months (which is not a harsh standard) - size too large for someone with medium to small waist sizes. I had to stuff clothes in the back to keep the pads on me. I hope there will be smaller size options based on waist sizes ... show more

  • Worked great for 5 months
This device worked great for 4-5 months until the electro pads on one half stopped working and the other half got really strong. Does a good job toning your abs while it works. Im buying another one of this style belt but not this one. I need a product to at least last 18 months.

  • Definitely Works
I bought this to accentuate my abs in combination with eating cleaner and working out more--primarily compound movements that involve the whole body/core. Sometimes when you start all of these things at once, it's difficult to know if it's the belt that's getting the results, or if it's likely only the eating/working out aspect. Because I wanted to know, I got a head start on eating clean and working out 3 weeks before getting the belt. I saw moderate improvement in my core. Having had the belt now for 1 week, I can tell an immediate difference in the size of my ab muscles. 2 x/day on Mode 2 at #11 setting (go big or go home!) in conjunction with supplementing with creatine, BCAA's, and glutamine to get a jump start on muscle growth has really caught me off guard how much the muscles themselves grew. Similar comment to others--I have a smaller size 30 men's waist, and I had to supplement with my own velcro strips that I bought at the store to get the belt tight enough. It's designed more for bigger people it looks like, so this is my only complaint. Otherwise--impressed with the results. I hope the durability holds up because I could see myself enjoying this for a long time. ... show more

i was looking for an ab belt as i find stimulation of some type of exercise to make me feel better. Ihopped on amazon to find an ab belt and I saw this one at the top of the list and was like why not. I ordered and it came about 4 days later which is actually faster shipping than usual for me. When i received the box i was instantly disappointed. it was a really small box but I gave it the benefit of the doubt. I then put on the belt and noticed it wouldn't fit. I'm a 40 waist and this thing wouldn't fit around me despite one review saying it fit up to size 48, it's more like a 36 waist size which is too small imo for the people it's targeting. i used a work around and secured item with a belt that felt dumb. I then sucked in my gut a bit and did manage to get it on. Next, finally, I got around to using it and i have to say that's the worst aprt of it. I turn the device on and barely felt anything. I have had exp with tens before and figured it wasn't a good connection. I put more water on my stomach and even then later used electrogel. it worked better but i still barely felt anything. I know what good current feels like and this felt like low settings of some other cheaper boxes that i've used in the past. On top of that It's not even USB -C meaning these power boxes are probably pretty old(i'm speculating there). the one redeeming factor of this item is i have to say the belt itself i think is nicely made. If my 500$ tens unit wasn't in the shop for repairs, I'd be tempted to hoot it up to the belt and see how well it'd work. i bet it'd preform a lot better with more power. for 80$ I think you expect a bit more than what this is offering. The belt i think is great and nicely made(despite it being small) but whatever is powering it is pretty cheap and bad. ... show more
