The set looked good at first glance. But then on the second use one of the pieces broke off and turned into a hole which I tried to drill. I didn't use excessive force or bend the racquet sideways. He just collapsed. And since he was in the hole, I couldn't get him out. He ruined an aluminum faceplate I was working on which cost me about $25. I decided not to bet it was just a bad moment, so I threw them all away.
