The 32" mirror looks good incredibly good when used behind a 36" vanity. The user manual isn't descriptive. The mirror is provided with a slim flat plug and is offset from the wall so it can be plugged into an outlet immediately behind the mirror. Once plugged in, the "Illuminate" button on the far left always glows soft white and I wish it were blue as it is annoying (hence docked a star). Turn the mirror on and long press the "Illuminate" button to either brighten or dim. "Click" the color temperature button on the far right to cycle between 3000K, 4000K and 5000K. We have it at 4000K to match the rest of the bathroom lights. 

It comes with a plaster anchor set and is quite heavy. I recommend using drywall expanding anchors if mounting into drywall and. Try to find a way to get at least one set of screws into studs.
