I purchased this faucet to replace my 5 year old Pfister that failed in several areas. The install was simple and straight forward but required two people simply because you need someone to hold the faucet while you tighten it down. I installed it on my four hole granite countertop. 

The faucet works well and the pull down feature is a plus. Getting used to the single handle faucet is a bit of a challenge if you switch from a double handle type. Not a big deal though. The soap dispenser is an added plus. I was a bit concerned about water leaking around the base of the faucet from dripping wet hands but it comes with a seal to install under it. No leaks at all. I did not need any type of sealant or silicon for the install. Great faucet, great features, and great design.
