Bought to replace my faucet same model three years of age (very hard water) so the damaged membrane no longer allowed to fill the tank in less than 20 minutes ... The mechanism is, despite my failure due to the hardness of my water, well made and sturdy. Hunting dual pressure (single or double amount of water) works perfectly, and allows beautiful water savings for the planet. Dailleurs, after 3 years, the part flush for its part is always in perfect condition and I was never a problem. The button also perfectly held since time is always like new.
Would recommend, robust inside and outside, and pretty.
