Installed today. Works great. I put up with a low flow faucet for 21 years. Changing the cartridge did not help. But now when I finally took the old unit out I discovered a kink in one of the three 1/4 D copper lines that are really too close to the deep nearly unreachable screw/down center bolt. I suspect the plumper who initially installed the fixture caught the copper line with his open/ended wrench. A special large ID pipe socket may have helped. Or, he might have used a piece of pipe before the bolt as a spacer to tighten down the nut away from the copper lines. This unit is much easier to install. No special tools required. The flex nozzle and hot and cold lines all fit inside just one sink hole with the bolt/down on the outside of the hole making assembly easy. I put soap dispensers in my two extra sink holes rather then buy caps. I doubled my water flow rate.
