The faucet was fairly straightforward to install and the instructions were easy to follow.  Great features and it makes clean up easier when your hands are dirty. I purchased a power plug and wall mount kit as well.  Highly recommend getting both.  I did see inconsistencies between the faucet instructions and wall kit instruction.  In my case I am replacing a 3 hole and wanted to more securely fasten the faucet to the sink base.  One set of instructions showed a rail that would give the faucet more stability and the other set made no mention of it.  Of course, it wasn't part of the items in the faucet's box so i will call Moen to see if i can get this part.  It will cause me to uninstall my disposal but probably worth using the rail in the long run.  Also, the faucet will not function without power, seems odd as I know the competitor will at least dispense water if power/batteries are dead.
