The valve gets 4 points in price money. I had an identical Model 5 years of service, after which it had in the scrap. For 35 EUR purchase price that's fine.
Particularly sensitive is the height adjustment of the hand shower; this is inside such processed filigree made of cheap plastic that any vigorous tightening leads to breakage. The resistance to hard water is only rudimentary, the nozzles are also not useful to clean / descale. The shower hose also has advance quickly to rust.
But as I said: For the equivalent of 7 EUR / year in a rented apartment that is absolutely ok. Who wants to be "good" private bathroom equipped therefore, prefer to reach more durable valves.
