Rated 4 out of 5 by 11 reviewers.
Rated 1 out of 5 by leaking again It was easy to install and a fair price, but it is now leaking again after only using it about three weeks. It doesn't leak nearly as much as the old one I replaced, but it is still wasting water. I'd love to return it, but threw away the packaging after I replaced the seal. November 4, 2014
Rated 5 out of 5 by Toilet repair Gasket fit perfectly and leak was sealed. Simple and easy to install. September 16, 2014
Rated 2 out of 5 by Running again Used this replacement on my toilet and it stopped it from running, for a couple weeks. Its running again now. I will probably try to get my hands on a factory replacement to see if it makes a difference. The fact that it worked for a couple weeks, leads me to believe the seal was the problem though.

Rated 4 out of 5 by Good merchandise Easy to install & keeps the toilet from leaking or running. July 22, 2014
Rated 5 out of 5 by easy to install Very easy installation. The installation video tutorial is pretty good, but they show replacing the seal on a unit that has been removed from the toilet tank. With some care, you can avoid that step. I recommend watching the video first to get a general idea on installation. June 16, 2014
