The installation of the product was quite simple. Even after the first use I was very happy, until I looked under the sink in the drawer. There water level in the drawer. Of course, at first I thought the fact that the Assembly was not OK, and that the connections are tight. But this was not the case. Water flows after pulling out of the faucet along the tube through the opening. The opening is quite large and also not sealed. Here I would like to see an improvement.
