My problem was ease of installation. As I was replacing an old Hot Water Tank, I was given the news that the hole for the faucet was not large enough for the new tank pluming lines. So had to hire someone else to enlarge the hole in my granite counter top so the lines could be installed. A feature I don't like is the ability to swivel the faucet to the side out of place if necessary to use that side of the sink. Otherwise the operation is fine. I like having instant hot water which is why I replaced the one I had. I understand there will always be issues in any construction.
