I bought this faucet 4 years ago worked fine until last year when one of the waterlines gave out and needed to be replaced - not a job that I could do myself - so while the part was inexpensive, the repair was not.  Recently over the stem rotation became a problem - now can’t move the faucet from side to side and believe I’m looking at another expensive repair or complete replacement.  Have other Koehler products that I’m completely satisfied with - this one, I think is a lemon!
