The Command medium size hooks have worked great on tile and wood paneling. After one day I was able to use and hang bags in my bathroom (bags full of perfume and lotion). I also used the hooks to hand a hairdryer and curling iron. They worked great. It was a complete disaster on walls (drywall). I tried it in three different locations. The first one fell off in one day without even having anything on it. The second one lasted a week, and again no weight on it yet. The third one fell and took off some paint and drywall and again I didn't even put anything on the hook. Don't use on walls!
