I expected some time of use to give my opinion. Nothing to say except that I have a lot of limescale that remain despite the shiny appearance. Therefore, when I'm not too lazy, immediately after closing the tap, I pass a cloth shot. But you have to have good time! Otherwise, very good handling the mixer. A 'visitor' can open the tap ignoring that there is a possibility of having a large flow and it is reassuring for consumption. The "click" is heard well when going wholesale rate mode. I made a professional for installation. No problem.
