We have been using this faucet for a couple months now and we love it.  Simple to use, efficient, and more than we expected.  More in the way of being functional and in the massive size of it.  The convenient way it works over rides the really-a-little-too-large-for-our-small-kitchen look of it.  (The high arc neck is 3 1/2" around to house the pull down spout.  And the other parts of it are large too.)  We received the faucet in a timely matter, my husband installed it without too much swearing, and it went to work for us without  the necessity of a learning curve.   The single handle is great and works in a most delightful way.  We have not experienced any change in water pressure with it. In fact, the spray is quite powerful. I recommend this single handle faucet.
