The ends of the buckles are so bulky that they don't easily fit through the belt loops. If you adjust it to a certain size and then pull the ends together to buckle it, the elastic slips through the buckle too easily and often doesn't stay taut. If it comes loose, it defeats the purpose of the elastic strap. What, as they say; I've worn it 10-20 times already, so I'm still experiencing it. Your other belts are amazing so I'm still hoping to get this one to work as well.
