Query: Not too bad

This works very well. East on... kind of tricky to get off, and after a while the paddle spreads out a bit from use. The inside of the paddle section has a kind of lip that grabs your pants or belt, making it unlikely that it will fall off. The problem is that it makes it a pickle to get off. Not unreasonably so though. Good for the money and entirely functional.
