So far, so good!
Glad I went with this - had issues with my toilet running constantly and the noise was driving me nuts, it was recommended that I try replacing the fill valve and flapper. The instructions were super detailed and easy to follow. I needed the 2” flapper size, so I just had to remove a few pieces to convert it (it came assembled as the 3”). Fit perfectly and my toilet isn't running anymore so I'm happy.

Quick and easy repair
We had a toilet that was running off and on so I wasn't quite sure what it needed so I purchased this kit. It was so easy! 100% recommend. Great directions too.

Fluidmaster Super Flapper
Super easy to install and takes the guessing out of flapper size. I also love the 10 year warranty!

Good Valve, Poor Flapper Fit
The instructions were straightforward and easy to follow. The fill valve worked just fine, but the flapper did not seal well and kept letting water leak through. I followed the instructions and tried troubleshooting, but it still did not fit properly. Since I mainly bought this for the fill valve, I put my old flapper back on, and that fixed the problem. I like the idea of an adjustable flapper, but it was not as universal as I expected. I bought a non universal model (same brand) for my other toilet, and that one worked just fine. So this is not a knock on the brand, just this particular model.
