Very easy to install, solid metal, well made! Highly recommended. We had a 1 1/2" hole cutout in our granite for this, but it could even take a 1 3/8" or 1 1/4" to make the fit a bit more tight -- but the bracket on the underside is strong, so the hole cutout we had worked just fine. Comes with the supply hoses, so save yourself the money and don't buy these.
