This mirror is so much better than what I have been using. I'm a little embarrassed to say, I thought I had my chin hair under control - this mirror shows all! I like the built in light, it has 3 settings and I rarely need the highest. Definitely use new batteries (3 AA) I tried to reuse some and the light wouldn't turn on.  For its size it has a fairly small base, less than 6 inches. The curved mirror makes it very easy to see all sides of my face.
