Great product!
Easy to install and worked great for fixing my running toilet. The fill valve adjusts easily, and the flapper has a good seal. Everything needed was included, and the toilet is working much better now. Good quality for the price.

Easy install, good manual, good value for a combo pack.
Good value for combo kit - at present I only needed the valve, but past history says I'll need the flapper some day. Quiet flushing, easy to install if you make sure to turn off the water and flush once to empty the tank. Have a small bucket and a towel ready. Has all the adjustments for a "normal" household toilet, and the manual is well written and easy to follow.

Great replacement
Installed it and it was preset to the proper level for me. Fills quicker and is quieter than before. It was straight forward to instal. I have never messed with the toilet before and I didn't need the instructions or any videos and I figured it out. If you need to replace a old fill valve this one will do!

Happy customer
Easy to install and works perfectly. The flapper didn't fit our toilet but the other part is a perfect fit and works as it should. We do not notice any "loud noise" and it seems durable.
