Big improvement
The "Universal Fits 99% of Toilets" claim holds true. The height adjustment feature is incredibly simple to use, and it took me less than 15 minutes to install it myself. The instructions were clear and easy to follow, which is a huge plus for anyone who isn't a seasoned DIYer. What truly sets this valve apart is its quiet operation. The name "QuietFILL" is well-deserved; my toilet now refills with barely a whisper. It's also very efficient, filling the tank quickly and without any leaks. Overall, I highly recommend the Korky QuietFILL Platinum. It’s a reliable, easy-to-install, and exceptionally quiet solution that will solve your toilet-filling problems for good. It's a small investment that makes a big difference in the peace and quiet of your bathroom.

Perfect valve replacement
Super easy install. Works great. It happens to be the exact same valve that came with the toilet.

Not as quiet as I had hoped
Purchased to replace an existing Champion 4 fill valve (FM-400 - snoop around and you’ll quickly realize what brand “FM" is) in an American Standard toilet. The Korky fill valve fits but I can’t say that it fits “well” in this toilet - it’s pretty snug in its space and I had to cut the fill tube very short otherwise it would impede the upward movement of the flush arm. I’m not a big fan of the metal clip design (that’s inserted into the fill tube); kudos that it’s metal but, IMHO, it should allow the end of the fill tube to extend further into the flush valve so that the water flows more directly into the flush valve and less likely to spray elsewhere. Also, if you don’t insert the metal clip *deeply* into the fill tube, you might be cleaning up a mess after small streams of water squirt all over the wall and floor (yup, that was me). It was quite easy to install and the installation directions are very good. Having installed fill valves in the past, I did not need to watch the referenced video - the written instructions were perfectly fine for the job. It’s nice that it is U.S. made and the price was very good compared to others. Lastly, this fill valve claims “QuietFILL Technology” but I fail to hear how this is quieter than the fill valve it replaced. Given the design of my toilet tank, I will not purchase this fill valve again when another of my 3 identical toilets needs a replacement - it just doesn’t fit well in the tank and it is not any quieter than other fill valves I’ve tried.

Easy to install and works great
Install this a little while ago and it's still working great. I wanted the heavy duty model but they did not have it in stock. Either way this one is doing the job and works every time

Better than original
Installed on a one piece Glacier Bay dual flush toilet and it works great, fills fast and quietly also like the fact you can adjust the water flow level in the bowl.

Easy to install valve!
Just finished installing the valve. Clear instructions easy to install. Will follow up on durability. I just noticed when installing that it is supposed to be a made in USA product. Hopefully it is a quality product.

Muy buen priducto. El ajuste de nivel de agua es muy fácil gracias a que tiene una marca que lo identifica. Ya no hay que estar ajustando la cantidad de agua que ingresará al tanque. Quedó listo a la primera.
