Pretty nice.  As others have stated, the seat does wiggle a little on it's mounting bracket.  One star off for that.  And I did have a rough time with installation.  I think the previous owner of the house cross-threaded the water hose onto the plastic threaded pipe on the bottom of the tank.  I could not get it installed without pulling the toilet and uninstalling the plastic threaded pipe on the bottom of the tank.  Metal fitting on a plastic pipe is just asking for trouble.
