I'm very disappointed in this product! I love the switch that controls the brightness, but that's its only good feature. It was difficult to install and use. The swing arm and mirror and very stiff and hard to adjust. We even tried using a lubricant on the joints, in hopes that would loosen it up some, allowing me to  manipulate it more easily--that didn't help. The magnification is nice, but unless you are about 3" from it, your image is distorted. I wish we could return it, but already threw away the box, etc. In my opinion you should save your money.
