Easy to install. The only obstacle was that I have a Backsplash on my Quartz counter top. The standard hole was too close to the faucet so the lever would not move. I had to design a spacer to raise the faucet high enough to clear the back splash. The threads were plenty long enough to accommodate the extra height required.
The first week we had a plastic task in the water but once it flushed through a few times that went away.
