Review on Single Hand Mixing Valve Ceramic Cartridge by Junior Samson

I was sad to discover my kitchen sink was leaking the other day. I went to a regular plumbing store and heard that the only place they "could" sell the Grohe brand was about 30 miles away. I did a bit of digging (disassembled the faucet with no parts) and found the model number of my sink. I ordered this device and the next day it was happily at my door. I've rebuilt the faucet before (in case anyone needs water) and the old one hasn't lost a drop since getting the new valve assembly. It seems that the new valve directly startled the old valve. Now I have a backup just in case.
