Major defects found upon startup:
-1- The "foamer" not "foam". It has a sort of grid; but the water jet is worthy of a garden tap!
-2- The airlock control knob is very very ugly: it is only a curved rod, no nozzle finish.
-3- Fixing metal half-slice is not sufficiently enveloping, once tightened, seals in place, the valve is not kept straight but leans on the side of the screw. I plan to make a more adequate puck because, as the tap is high enough, it is really unclear vertical (I said that the media is flat and sufficiently rigid)
-4- There is no connection in the packet for a flow of overflow ...
-5- It would be nice to have the choice of a left mounting template for lefties!
In short, I can not recommend this faucet.
