I got this on the day that I was having a birthday party for my 80 year old mother. I installed the seat, which is very easy to do -took only about 10 minutes (must off that time was gathering tools and removing the old seat.
     My wife was so impressed with release feature she showed everybody that came for my mother's party. Thanks a lot guy's I had to go out and buy 6 more of these for my mother, my pregnant daughter and some friends. Great item I would recommend to all.
