Great but.... So beautiful....such a great functional shower.. super spray, Great water pressure. Just really great except for one thing. It makes a clicking sound when any other water is turned on upstairs....not long in duration, just when the faucet is turned on or off. Ordered a new cylinder because plumber thought it might help (69)....it did not. So, we live with the click. Odd. But everything thing else about this shower is GREAT.  The manufacturer was NO help. Impossible to reach and never replied once I found their service help contact info.
