Review on Pfister 9100320 Cold Faucet Cartridge by Ryan Carter

I wrote a 2 star review on these handles on the version of these handles that includes a hot handle (9100310) and a cold handle (9100320). I also purchased two more cold stems for this product. Crowd. And now I have three cold stems, unused, in the original packaging because I tried using the hot stem on a Price Pfister Treviso 1/4 turn blender and couldn't stop the stem from leaking no matter what I did. I previously replaced the cold stem on this faucet with a $12 Danco 3G-3C brass stem from Lowes. And I only bought the entire stem from Lowes because they didn't have the precision o-rings, washers, etc to rebuild the original OEM stem. But trying to save money for future repairs, I bought one hot stick and three cold sticks. I tried replacing some of the washers that came with the 9100310 hot stem and reused the OEM brass stem housing. I finally gave up, went to Lowes and bought a Danco 3G-3H stem which worked great. Now I have three of these 9100320s that I don't want to use. make me an offer ;-)
