Good quality valve (sy is expected for the Grohe). However, impossible to put the maximum score for two negatives: - Design of the ineffective zipper: this faucet is sold with a zipper consisting of a chain to which is attached a small weight. As I was ineffective after this assembly, I recovered the zipper (composed of a rod) replaced the faucet after a few mod, was adapted to the new faucet. - The U-shaped piece which allows the tightening of the joint under the basin is of a slightly too soft metal. The room was writhing under the clamping pressure and did not provide a good seal. Again, I had to retrieve the similar part used with the old faucet (Grohe also) that it was made of brass. More flight thereafter. Conclusion: some 15 more expensive I recommend the model above (# 32925), which provides real rod (rod) and a more efficient saver. By cons regarding the U-shaped part, I doubt it is because of better metal.
