Have this faucet combined with a Quarzkomposit- sink from Ikea, which is also flat black. Delivery was fast and installation was easy. I therefore can not understand the other two bad reviews. The valve acts not chunky, but is compared other fittings rather decent. If you stick strictly to the instructions, the installation also can not go wrong. I recommend the connections do not have to tighten, otherwise go the seals broken. The shower hose can of course only work properly when it is not kompromitert of other parts which are under the sink and the weight was placed in the right setting. I have to bring an extra taken other Schläuch aside so the shower hose can rotate freely. vg
