I am very impressed by this faucet. It was fairly straightforward to install and works very well. The manual is detailed and it has all of the info you might need, including cleaning and troubleshooting the valves if necessary in the future. Things that I liked: - Very good build quality and feel of the valves. Solid and sturdy. - The drain separates in two between the bottom of the sink and the stopper lever. This allows you to install the drain without having to unscrew the flange on top. This makes future removal much easier and prevents potential damage to the sink drain opening. - The valves are fully serviceable\replaceable. This also allows you to tighten the handles if they ever become loose. Our previous faucet had fixed handles which eventually started to separate from the valve and cause dead zones. - Drain section is plastic. One might consider this to be more of a con. However in the long run it would prevent potential rust buildup which causes the retaining nut to freeze up. - The tool to remove the aerator is included for easy cleaning. I can't really think of anything I am unhappy with. Only time will tell how the valves perform but that applies to every faucet on the market.
