Rated 4.7 out of 5 by 17 reviewers.
Rated 5.0 out of 5.0 by This is a great investment If you buy the black flappers because of the price,you are wasting your money.The red flappers last longer,because of the chemical resistance built into them.With the cost of the running toilet it's worth the cost. April 14, 2015
Rated 5.0 out of 5.0 by Perfect replacement for Kohler Cimarron Toilet Replacement for part #1016546. Installation is very easy! Perfect match for my Kohler K-4634-AA toilet. July 23, 2014
Rated 5.0 out of 5.0 by Flapper Installation The flap was installed in a matter of minutes andn worked flawlessly. The issue is I replaced an identical one about a year ago and I thought it should have lasted longer than that. One hint....if you have two idenitical toilets replace both flappers as this will give you piece of mind that both are replaced. One other thing. Mark the date on the flapper with a "permanant Marker" so you know when they were last installed. Finally, take the old one in the store with you as there are a number of flappers that closely resemble each other and only one fits...might save you a trip back to the store. January 27, 2015

Rated 5.0 out of 5.0 by Perfect Fit, Quick to Install Bought the product a few weeks ago to fix a running toilet. The old flapper was not holding its form. Worked perfectly. I wish all repair jobs were this quick and easy to diagnose and repair. February 17, 2015
Rated 5.0 out of 5.0 by works great no problems went right into toilet five minute to install very happy December 24, 2014
Rated 3.0 out of 5.0 by Product fine, accessibility poor. The product, a toilet flapper was satisfactory. I was not happy that you didn't carry it in store and was not available for in-store pickup. Shipping cost almost as much as the product itself. July 17, 2012
Rated 5.0 out of 5.0 by Perfect fit - original parts Easy to install because of a perfect fit since it is original parts. September 2, 2014
