    5.0 out of 5 stars Better Than The Standard Model

    This model provides many more adjustable features than the standard flapper. It's higher quality rubber, has settings to fit just right, and no worries about leaks. Worth a little extra money...

    Easy to install, good quality and the price is reasonable. Order this to stop water leaking from tank into bowl. You'll save having to call a plumber!

    The one the plumber put in the tank was too big and so the water kept trickling down the hole and was causing the tank to use more water than needed. So I took it upon myself to get a new one and put it on myself and it fit perfectly and now there is no more water trickling and the tank does not need to refill until we flush the toilet.

    The band adjustment is difficult out of the box. Once I lubed it with silicone spray, it moved easily. An adjustable flapper is a great idea, I would prefer the adjustment wheel be on top of the flapper, so the entire flaper doesn't have to be removed to adjust it.

    Needed to replace a leaking flapper, purchased this item. Followed instructions, measured my existing flapper, ordered perfect size, super easy to install, no leaking, works perfectly for $6. Saves plumber bill.

    1.0 out of 5 stars Manufacturing Defect
    Reviewed in the United States on December 18, 2024
    Ordered a pair of these flappers. The main open/close adjustment was locked into the closed position and impossible to turn to the open position required for a 1.6 gallon Kohler. Factory video demonstrated that it should be very easy to turn. The fine adjustment was too loose and would not stay in the proper position. I am sure that some people just install these without reading the instructions and don't know that it is not working properly. Don't waste your time on these defective flappers. Waiting on ups to pick them up now.
