First of all you should know that I'm very picky about my Keystone. I used about 200 of these on my last install. with a platter to place the keystone on while you punch it so you don't have to place the keystone on the floor or against the wall. Makes stamping a lot easier. When you're ready to place them on the wallplate they snap easily into place. I know I've bought keystones in the past which are very tiring on my fingers. Overall they're solid, simple and feel good the hand .
