I actually won't have the band till sept or October. But I have user the body bugg generation 1 before I considered the band and with its help I lost 60lbs. I love the bug. My bf just bought it for me for $99 online it's on sale till June 15th by the way it usually sells for $250. If you really want something to aid you in calories burned dedicate vs calories ate which u record online via the program u get and know what you need to do in order to lose weight this is the tool for you.
