This belt is a boon for those who, like me, never had enough backs to hold up their pants. All the leather straps I've had are stretchy and uncomfortable. This belt serves its purpose and is very comfortable.
Pros
When used correctly, the trousers are guaranteed not to fall off.
Cons
The elastic belt buckle may not provide enough support to keep the belt securely in place, resulting in uncomfortable slippage or belt gaps.
