I put these in all my bathroom sinks (7 of them) when we remodeled. Scroll down to see their video.

I really like not having the little pop up lever on the faucets and the mechanisms in/under the sink that rust and need to be replace every few years. I hated that project!

The only issue I found with the zerodrain models is that if they aren't used very often they can become stiff, so I recommend that once a month you pop them down/up a couple of times and wipe them off to get any hardwater deposits off. I still really like them and would use them on any future projects.
