Installation is simple. Cold and hot water supply hoses bit short (ca 30 cm, had to extension at the hardware store to buy).
2 stars because:
The faucet is incredibly loud. The water flow is clearly audible and is not insulated acoustically through the minimalist design.
Since 3 weeks, the water tap at the opening sprayed sideways when fully turned up on him. After such a short time is unlikely calcification.
