Great mirror and easy to install - it was on the wall in 10 minutes.  The only problem is the battery life.  It takes 4 batteries and they are out within 2-3 weeks with little use.  The light automatically turns off in 2 minutes and I might use it 2 minutes total every day.   If you buy it just stock up on batteries because you will need them.  Otherwise the mirror itself is great.  Maybe one day I'll get an electrician to hard wire it - if so I'd give it 5 stars all day long.
