This faucet functions very nicely.  The installation directions seemed to be out dated. There was an unnecessary assembly step (#4) included.  There was also an extra part (plastic washer) that not listed in the package contents but needed as part of the installation.  I figured it out and the faucet works fine. The handle comes loose and we have to keep tightening it (by hand, no tools required) but it’s a relatively minor thing.  We like this faucet.
