When the faucet was stiff and drooling at the sink, I went to explore in Hardware Internet. Now, the new valve is assembled and I'm happy. As already described by many users, the fine adjustment is certainly a major plus. Stable-acting base and pleasant high inflow arising shapeliness, all in all a nice part, and cheap to boot. Was that the connection of hot and cold is not specially marked - well, with items, blow with a corresponding tap position you get out there also. A small hand spray with IG M 22 x 1 I had to buy elsewhere - but now I love my new single lever kitchen faucet Cosmopolitan Grohe => absolute buy recommendation!
