  • Awesome Results!!
I honestly didn’t know what to expect from an EMS trainer off of Amazon, but I was pleasantly surprised. I have been using this device every day since I have bought it on different areas of my body. Even though it is for abs, and while I use it for that purpose, I also am able to attach it around my hips and use it for my glutes as well. I have lost around 15 pounds since starting this, however, I have made some slight diet changes as well. This is not a miracle worker for weight loss. You have to put an effort in other areas to. If you are doing other exercises and eating more mindfully, this is an excellent addition to burn extra calories and train muscles, which in turn burn extra calories while you are not working out . I am very impressed with the outcome and I will continue to use this device and I will update my review when I have reached my goal weight. I fully recommend you try this product if you are committed to making the above said changes. I also want to mention, that it runs for days off of one charge. It has so many different modes and settings, so that way your body does not get used to the same setting or the same intensity so it is continually building muscle and avoiding that plateau. ... show more

  • Disc module inop
Purchased this belt type because I purchased a gel type 10 days prior which was the worse. Gel pads curled, would not stick after 4 days. Nothing from that seller. So I purchased this belt type, which is a lot better. Power module never worked. Good thing that I had the power modules from the previous unit. Snapped in place. Sent the seller a message on the failed disc two days ago. Never heard a response. As usual from some of the sellers in this site. They just want to sell a product, collect the money and move on. 2/22/24, after a month of use. Do not waste your money. These things do not do what they advertised. Do little if anything for you. ... show more

  • Quality built with good intensity
After trying several different ab belts, I reordered this one due to the quality of build and intensity of workout. I had to return two other belts due to electrical connectivity issues or lack of intensity. The velcro strapping is strong, sewing on pads is quality, and materials used make this feel like it will last a long time. The controller battery lasts about a week between recharges with regular use. If you're looking for a good quality ab belt with decent intensity at a good price, this is the belt. This belt uses two large conductive pads targeting the rectus abdominis muscles primarily. I found the belts that use 6+ pads to target more muscle groups lack the intensity required to get a decent workout. ... show more

  • I need wieght loss
I think that since we are trying to slide wieght it means I am larger than I would like to be but it is to small you need to make them larger even if you have some added Velcro extension that will get you to the shape you want to be

  • A shocking way to train abs Haha
I have been using for 2 days now. It is easy to use once you work through the vague instructions. I have used the belt 30 minutes each of the past 2 days and my abs are a bit sore so it may be working. Time and continued exercise will tell the tale. The price was GREAT! So far good bang for the buck. ... show more

  • the first one did not work. They sent me a new one with 3 to 4 days.
First one did not work and it was replace very quickly. It works great. I've been using it 2 to 3 times a day for about 45 minutes each time. The numbers for the level of intensity are not coming out clearly. Once you use it several times you know what level you are at. Can not beat the price. Very pleased with it. I do get by moneys worth. I'm going to order another one just in case. I do use it a lot. ... show more

  • Love it, but it way too big!
It works! I love that the material is flexible and softer instead of the hard plastic leather material of the one I ordered previously. It is way too big for my waist though. It’s also too wide. I wish it came in different size options. I’m thin, 28” waist with wide hips, so when I strap the belt on, I have to pull it down pretty low and strap it mostly to the elastic band with just a small piece of it on the actual velcro in order for it to fit, but that causes the stimulation pads to be worn lower on my stomach and it shocks my hips. Annoying, but it works. ... show more

  • Belt great power pack attachment sucks
The belt is a great design but the power pack is attached by two little snaps. Even if you are able to line up the snaps and fasten them it takes very little pressure for them to pop off. I’ve got bifocals and had a hard time getting the snaps to line up. It’s to bad the belt had a great design but they went cheap on fasteners. I returned it the same day. ... show more
