Removing the old three hole faucet assembly took 4 times as long as installing this one.  VERY easy to installs.  The materials are heavy and quality.  It looks sleek and I much prefer only one handle in a bathroom sink to get the right temperature every-time without having to adjust two handles.  The pop up drain is so nice and looks so much better than my old manual pop up stopper.  I highly recommend this brand and faucet.  Works like a dream and easy to install.
