OUTSTANDING
This is day one and I LOVE IT! Outstanding! Easy install, fast fill, works perfectly and quiet! If it has lasts, it will be the best in the world for the price!!!! I may change out my other bathrooms just to save the water and the quiet quick fill!!!

Works great with no leaks or fuss.
Easy to install, fit well in a Glacier Bay toilet (smaller tank size but had no compatibility issues). Seals perfectly well with hand-tightening, had no issue adjusting the length to make sure it filled up to the line on the overflow tube. It came with a little metal clip that grabs onto the overflow to direct water into it. It looked like it was kind of far but it's actually designed to have the water flow perfectly out of it. I cut the black tube to size in my case so it wouldn't push the device too hard. Had a few leftover pieces at the end. It even comes with a piece that will break off if you mess with the fill valve length adjustment (for tenant, apparently).

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.

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.

Excellent budget valve
I replaced my fluid master that was intermittently sticking. Simple plug and play, about a 20 minute job and no leaks so far. Easy to adjust the water levels of tank and bowl. Appears to have fewer parts and seems to be working as it should. Not any noiser than the old one. Can recommend so far.

Stop your running toilet today
Easy to install. Works great. It was my first go at replacing one and it was simple. Should not have waited so long thinking it was gonna be a big job.

Fast / Universal Install - you won't be disappointed
Super easy to install for most any height water tank. A quick 10 mins. Have purchased this multiple times to replace aging plumbing and is super quiet on refill

Don’t need to be a pro to install this. Easy!
I am not technically savvy, but was able to install this product without any problem in just under 10 mins. The problem we were having was that our toilet didn’t fill all the way after flushing. It would fill then stop, fill some more then stop, and then again. Maybe 8 times this would happen with each flush. We have 2 teenage daughters so when their friends would come over, they would have these weird perplexed faces as they exited the bathroom — on occasion they would ask me to check if the toilet actually flushed. It was quite embarrassing. Fast forward, I installed this and now the toilet fills quickly and very quietly. No more stop/starts. So it’s been working out great. Also, the adjustable height positioning works well for us as we have a very low toilet tank. Zero leaks from the install, so I can also say that the seal has been flawless for us.

La marca de nivel de agua ayuda mucho.
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.
