Well constructed. I ended up mounting ours upside down, so that the mirror hangs down below the base. I was able to completely disassemble the base and re-orient so that the switch was still easily accessible. (Instructions don't include this, but anyone of reasonable mechanical ability can figure it out). Just make sure your electrical box is well anchored.  Some DIY'ers might be tempted to just fish wire and hang this on molly plugs, but that would be a mistake.  The mirror is heavy, and would eventually break out the drywall. Attach it to a box, and run your electrical wire into the box (as required by NEC) and you should be happy.
