I tested this belt over 3 weeks and I confess that it works but of course that does not make miracles! I met 2 times a day, once up, once down abs (can place on each buttock, one after the other but we must remain standing is not made for!), and I see a clear improvement in the firmness of my abs. It must be on balanced eating and exercise a minimum next otherwise it has no interest and especially any results, do not dream, to have a nice belly it must go through a balanced diet (as often as possible ) and a bit of exercise every day (30min of walking enough). I do not find this painful (remember to wet the belly and waist before!), Rather pleasant year makes. You have to go gradually.
Disadvantages: the belt "scratch" hurts, you have stuck his shirt between the belt and the skin if it is unpleasant! Also, if you want to relax with your laptop while working the belt, do not place it on your lap! g tried several times the computer shuts down without warning probably due to electric waves!
Now you make your choice, remember that to lose weight you must make a minimum of effort!
