I bought this because it matched the new Toto toilet I ordered.  I didn't really have any expectations.  So I was pleasantly surprised when we installed it.  Just a tap on the back of the lid, and it slowly closes by itself.  In a rush, you can push it down more quickly with just a fingertip.  

I have a son who has always banged the seat up or down.  He can't do that with this one.  Very nice.
