I have been using the belt for only a few days but I am super impressed with my results I'm already seeing! I have had 5 kids and my stomach is loose and full of tiger stripes. Using this belt at least 40 minutes the last few days I am down 4 lbs and my skin feels and looks tighter. It's so easy to use, although a little big on me, I strap it on as I work at my computer and drink my water. After 20 mins, I use my vibration plate or I was out working in the yard or by the pool and that's it! Per instructions the belt needs shut off to cool every 20 minutes or it may overheat and malfunction however the belt timer goes up to 60 minutes... just don't understand why it has 60 minutes as an option which is why I docked 1 star. But, overall, I'm glad I purchased and can't wait to see my results with continued use.
