We've had these installed for 3-4 years in our master bath. One of the cold handles has started to become increasingly difficult to turn (as reported in other reviews). However, I wouldn't say this is an issue of the handle, but an issue of hard water (minerals) clogging up the mechanism. It's going to happen with any faucet where I live (SoCal). The only thing I do not like about this particular faucet is that the square edges of the spout, where the curved piece meets the flat piece have started also becoming gunked up with hard water deposits. (I.E., there's a seam that runs from the based to the spout.)
