Bought one of these belts a few months ago. I'm sensitive to metal buckles, so mechanical belts are a must for me. At first I was very happy with the quality, but one day the ball head broke off the mounting pin and unfortunately got lost. Of course, the return window had already closed, but since I really liked the belt, I took the risk of getting a second one. And the EXACT same thing happened AGAIN, and of course right after the return window closed. DO NOT BUY - FAULT GUARANTEE.
