We installed the faucet ourselves.  The directions were easy to follow however we did get stumped briefly on how to get the hose extender attached.  The directions could use additional detailed steps for those that are DIY'ers.  The quick connect and the faucet head both have to be removed to allow you to run the hose through, then reattach.  Once we had the faucet completely installed we loved it!!  The only negative is that with the height and weight it is definitely better suited for a kitchen with a stone countertop.   The faucet at the base doesn't feel as strong as if it was supported by a solid stone surface.  Overall it is beautiful.   Love the pull out sprayer head and the 2 selections of spray adjustments.
