This faucet thermostatic mixer works well. Temperatures are properly staged, the flow is excellent. However, there is a slight downside! The center tap, there is a pushbutton that can actuate either the water flow to the shower or to the bath. This axis is surmounted by a knob which is screwed above but which is not braked. Result, the button unscrewed over time and the screwing, shifting the eccentric shaft causing a blockage and prohibits the selection bath / shower. It is therefore from the implementation of the mixer unscrew the small button of the axis and put it back after the coating means no thread locking screw (without wanting to advertise, I used Loctite 243 suitable very good). I will try to contact the seller to inform him the inconvenience.
