Even though I am not an experienced craftsman, I was able to connect the valve without any problems. It all looks very high. The head of the rooster can be pulled out and the sink rinse well accordingly. I had in mind before the installation only if the runs smoothly because no hose weight was there. But even without Wiped no problems! The head of the cock can be traced back readily.
Conclusion: For the price unbeatable and super modern!
