Alot of people buy this expecting it to magicly create abs, the truth is if ur getting this to get rid of alittle bit of fat, don't buy it.. it's for people who have already got there weight down and diet right. If you already have a flatish stumach and want to get some abs, or u already have a bit of a 6 pac, this will drematically improve them. You do have to get used to it, at first like level 3 AND 4 feel a lil mental really "vibrating" ur abs, but after like 10mins, i was able to put it up to like 5 or 6 and was getting good contractions without doing anything, my abs felt worked.. i'm sure they will be hurting tomorow morning, i will use every evening. so yes this thing does work, you only get a small tube of gel, don't no what ill use after. you get 2 batteries, only one required so a spare one,. for £5 it's really good, i suppose time will be the real test, but just for now i think it's very good.
