I thought this belt would fix what other mechanical belts do wrong, only one prong holds it together, but I was wrong. Due to the lack of a loop on the inner buckle to keep it on the body, it popped out when I leaned over, panted, or moved in any way. Which made it completely useless as I'm an active guy and need to keep my belt buckled while sitting at my desk or working on a truck. Returned with a full refund and was looking for a two tooth one loop belt.
