Has anyone used those "Kitty Caps" - little plastic covers for cat claws?

One of my cats loves to wake me up about 2-ish every morning by clawing the carpet, the bed, the throw rug – anything to be destructive. I usually get up and shut her up in the far bathroom so I can’t hear her complain, but this is really old. I got some of the little claw covers – I think I got them on okay, but was wondering if anyone had used them and might have some tips for me. Thanks!
