A nice fill valve, helps keep toilet tank clean as well.
a nice toilet valve. I love the feature that keeps the bottom of the tank clean. It was easy to install, did not leak, and is still working great.

Use this valve
I broke my toilet fill valve trying to figure out why it wasn't feeling very fast so I ordered this and it was extremely easy to install, a very good price, and so far it has been far better than the old one. This fill valve seems to be very durable and is very easy to fit in the tank. After getting it completely situated and following the instructions The overall accuracy of it fills to the exact amount that it is supposed to and The shut off valve is quick and easy. When I need to replace the other fill valves in my other toilets or if I have to fix someone else's I will use this one again. It is just so hard to beat the best price and high quality that this toilet fill valve offers.

Saving lotsa H2O
It is a little different in design now. Worked better for me. It has holes are directly in the tube instead of having wider plastic tube so I was able to drop it behind the flapper area which is very close to the back of my one piece toilet. It is noisier than the original valve but is "wooshy" in a good way IMO. It turned out to convert my toilet to a 2 stage flush which I was interested in anyway. If I give the handle a quick tap it uses even less than the 1.6 gal it was rated for. Great for number 1 and more. Ate a lot of fiber? Push and hold a moment for more extensive water results or hold it down for the "5 golf ball" flush (haha, never tried it, but, it says it will). I am saving about a gallon just on the bowl filling valve so I don't have to pee in the sink anymore to satisfy my quota of "PC" anymore during the drought, which is a good thing since that sink is downstairs and dangerous things might be lurking in the dark and cold basement. Not to mention the low headroom and funky stairs. Anyway I digress. It seems about the same quality as most of the plastic valves I have seen. Time will tell. I bought it for the water saving aspect and was rewarded handsomely. Stars come off if it breaks in less than a year since the original took a licking and was still flushing happily after 7 years or more. Only suggestion I will recommend heartily is if your flapper valve is raised up from the base, as mine is, be sure you ether pump or vacuum the water out or have a really large container. I had about 1-1/2 gallon of pans ready and there was probably another 1/2 gallon or more in there and it comes out FAST! Probably didn't help that I spilled one of the pans after I realized I had seriously under estimated the amount of water in there trying to dump it in the bowl. Now I have a bit of drywall work to add to my burgeoning to do list.

Amazing Green Product
After reading reviews and needing to repair one toilet and update the other I decided to purchase this. It was the best choice I could have made, it does everything it says and it takes no time to install. The cleaning tube does just what it says, after years of using dropins and such products the buildup sits in the bottom of your tank, while making adjustments and about after 4 flushes, the tank was clean of all that buildup. The sound is that of a new toilet, I will purchase another one of these for my other toilet along with the flapper, which in such a rush, I did not realize you could get the whole set. I did purchase the flapper, and it works great as well and instructions make installing a breeze. The original toilet I purchased this for needs a tank to toilet gasket, which I did not realize until I put this one on, I had not used it for years and the water was off, and I did not know was leaking,so I took it off and put it on the other toilet, I can honestly say, with taking out the old flush valve and installing this one it did not take 10 minutes total, the instructions are very clear and concise. If you want to upgrade your toilets without spending a lot of money or buying a whole new toilet, I highly recommend this product. I will also purchase the dual flush converter on the other toilet to get the full effect of this product, and from using this I can say I look forward to installing it, and waiting on my guests responses about my new toilet, which is actually what it feels like and sounds like , it was a fun experience and seeing the finished results I am proud of my purchase and look forward to giving a review about the dual flush converter once I purchase and install it. You can also see how much water you will save by the amount you are using with the adjustments compared to the older flush valves, the sound and the way the water swirls in the bowl you can tell the difference in the power you get with each flush as well. Other than loving this product and looking forward to experiencing the benefits of using it and upgrading my home at the same time is a plus. Thanks again Amazon for making my purchase experience a unique and rewarding one.

I wasn’t sure about the tank cleaning tube but boy does it ever do a good job or keeping the sediment from accumulating in your tank. Easy to adjust for water level installation was a breeze reasonably quiet. Really pleased with design

The unit works great and was easy to install , everything was great except for the bottom retaining nut that connects the toilet fill valve to the bottom of the tank. The one that comes with the unit isn't one you would tighten with a wrench it's a hand tight only kind of peace and that I couldn't get tight enuff to not leak, it has these little plastic arms that stick you and you're supposed to use them to hand tighten it down. But on mine there wasn't enuff space so I had to trim them doing that made them a little sharp and couldn't get it tightened as much as I needed so I used the plastic nut that I took off the old failed unit and I was able to tighten it down properly without any leaks cuts or clearance issues hope this helps , Good Luck

Works very good, there is no problem installing. I do like the valve overflow adjustment as we are on a well.
