The handle was slipping on my Atrio bathroom sink. For a few bucks, this provided a simple, easy fix that works perfectly. It took me and my 3-and-a-half-year-old assistant about 5 minutes to replace the old one, and most of that time was spent explaining to her how the sink worked. I'm going to buy a few more as backups in case we have the same problem on one of the other sinks.

Part was received promptly and worked great. Difficult to locate part as part number didn't produce search results.
