Couldn't recommend to replace existing faucet can't see how someone could get 2 wrenches on valve bodies from under an installed sink in cabinet. I've gone nuts installing drain lift rod it comes down and bumps into spout hose connection and then when lift rod strap connects...adds more interference.Look at diagram 18 or 22 in your instructions to see. Also teardrop shape of top lift handle has zero clearance to back splash. Still not working smoothly. Single handle faucets come with pop up drain plug, why not these? Invisible plastic aerator with plastic wrench, wonder how I'll get these out in a few years when calcium deposits build up.
