This is my new favorite thing for making life just a little bit easier.  The mirror has very good clarity and is just the right size.  It is very sturdy and attaches to the wall nicely.  The arm is a bit stiff to stretch in and out (which I'm sure can be resolved with some oil)--however, it swivels nicely, so I just swivel it back to the wall and never need to adjust the arm.
I don't know how I ever lived without this thing!
