I wish the opening to put the leather strap through was bigger to fit more bands easily. The corners around the hinge are kind of sharp and scratchy. Everything else about the clasp is very nice and comfortable. 4/5 as they could've rounded the corners more, and even made the opening bigger.
I've used this clasp for a few months, and knocked it about quite a bit. So far so good. The coating is durable, and I'm happy with the quality.
