The faucet is a quality item and solidly built and finished. The installation instructions were easily followed and made simple by the quick connect fittings. However the instructions were unclear when using the deck plate for a 3-hole sink. The grooves in the deck plate are supposed to line up with bosses on the bottom of the faucet but there were no bosses. The faucet rotated on the deck plate and would not tighten up. I had to remove the entire assembly (not easy) and use a large o-ring (included for I-hole installation). The faucet would still not hand tighten per the instructions. I notched a length of 2" PVC pipe and used that as a tool to tighten the mounting nut. The faucet works as described and there were no leaks from any of the quick connects.
