   Just as good as the Cold Water ones I replaced (9100320) Purchased these after several of the Big Box Stores versions leaked upon installation. I should have bought these to begin with, PREFECT…no leaks. FYI…I did reuse the Brass Collar from my original unit. Make sure you orient the parts (on the new one) the same way/order as the one you removed.

   It’s the real thing. You just need to make sure it’s tightened down well, otherwise it will drip.

   Four stars because I can’t be certain how long it will last.

   Perfect fit and most important it stopped the water leak. Initially I though I purchased the wrong cartridge, but I found this was dual fit. For my faucet I had to slide off the white outer shell it fit perfectly in the faucet. Actually reading the provided instruction helps.

   I purchased this as a replacement cartridge for my Pfister LF049DK00 Treviso 2-Handle 8″ Widespread Bathroom Faucet. I found the correct part number for this faucet on the Pfister site so I had confidence that this was the correct replacement part. However, this replacement part was NOT the correct part. The original cartridge was much thinner such that the replacement would not fit in the housing. Obviously care is needed when determining whether or not this part is the correct one since information of the Pfister site can be incorrect. The attached photo shows the original “slim” cartridge and the new “too fat” cartridge rests next to it on the plastic wrap with the red ring on the top.

   This product was necessary for my kitchen sink. The packaging on the product was barebones, in a good way. It comes in a small plastic bag with a set of instructions. The instructions were, in hindsight, very clear. However, I did use a video to assist.

   To hire a plumber to do this easy fix would likely have resulted in over $100 so for the price point of this product it saved a lot of money.

   I have had the product installed for about two weeks and my drip has stopped and no further leakage as been noted.

   I highly suggest this product if youd like to save a few bucks and don’t mind spending about 15 minutes installing.

   Bought both hot and cold valves for my Pfister faucets. They were easy to install. Had them both replaced in about 15 minutes.
   PS there is an Allen set screw on the backside of the handle base that you have to loosen to be able to remove them to expose the valve and the brass nut that holds it in place.

    Appears to be the same quality as the original, and it fixed the leak for less than 8 dollars. What more needs to be said

    Worked perfectly for my bathroom faucet. My faucet has been leaking for almost a year now. Just a drop or two a min, but it was getting annoying. Whi knew it was this piece that was needing to be replaced. Installation was quick and easy and now my faucet is as good as new. Saved me a lot of money not having to replace the while fixture.

    I had previously installed two new replacement cartridges from another brand, and each time they would bind up and make noise when warm water was flowing.

    Third time’s the charm; I installed this OEM Price Pfister cartridge a week ago and now the faucet operates like new.

    Back when I bought the other units, I think I had been put off by the appearance of this OEM part. In our application, we have to remove the white sleeve before installing; it slips off the cartridge easily. Price Pfister illustrates this on a brief little repair video.

    In summary, this one works better, was delivered faster, and was cheaper than the other two I tried. What’s not to like?
