Very nice faucet out of the box. A great design for easy install. The faucet itself installs from the top; only thing to do under the sink was attach the water lines. The faucet and base are two parts; the faucet is held in place over the base by a small set screw. For my installation I had to place the control to the front because of a lack of space for a side install (the handle hit my window sill) which prohibited fully turning on the hot water. Turning the base for a front install caused another minor issue in that it placed the set screw to the back making it very difficult to tighten with the hex wrench (the set screw is on the opposite side of the control handle) because of how close it was to my backsplash. If the faucet turns into a lemon, will update the review.
