I hate to give it a 1 star because it could of just been a one time thing but i barely used the belt once or twice not at full capacity and for some reason the metal piece that goes in the hole on the belt that holds it in place just fell off it didn't bust off while using it fell off when i went to put it on. And i did not contact amazon because i did not have the time also i did not wear when i first bought for a week or so im sure they would have replaced it, but it was essentially a waste of money
