Review on Ceramic Hot Faucet by Pfister - Model 9100310 by Macaiah Arreola

I bought this cartridge to replace my Pfister LF049DK00 Treviso 2 handle 8 inch bathroom faucet. I found the correct part number for this faucet on the Pfister website so I was sure it was the correct replacement part. However, this replacement part was NOT the right part. The original cartridge was much thinner, so the replacement didn't fit in the case. Obviously care must be taken when determining whether or not this part is correct as the information on the Pfister website may be incorrect. The attached photo shows the original "thin" cartridge, next to it is the new "too thick" cartridge in plastic wrap with a red ring on top.
