The unit arrived before the projected arrival date, and I am completely happy with the service and product.  It is well made and substantial. The plumber took only about ten minutes to install as we had a similar tap before.  I like the 1/4 turn canister rather than old fashioned washer construction, and from what I understand of this system, it lasts a long time. Never drips, and is easy to replace.  One thing to be aware of,  there is a water saving device in the screen part at the end of the faucet.  When we first turned them on we were unsatisfied with the water flow which was minimal.  It is easy to remove this part (white disc), and the taps work fine after.  Lots of pressure when you want it.
