This is the first muscle belt I have ever bought so I did not know if I would like it or not. (turns out I do)
I have had the product for nearly a week, visually I cant see much change (only had it for a week and I'm not the thinnest person in the world) but I can really feel the difference.
it has 6 different modes and 10 strength settings.
its also not just for your abs it comes with a list of areas it covers ranging from neck to buttocks.
the only problems I can think of with this belt are as other reviews state the battery compartment is loose and you don't get much of the gel so use it sparingly (or buy some more I'm just mean when it comes to handing out money)
all in all if used correctly you can get some great results out of such a cheap item
