I had bought 2 mirrors prior to this one and neither was quite right. I actually found this mirror after a hotel stay and I ordered it immediately. It’s perfect. The light comes on when you get close to it or you can turn it off and on with a small button on the piece that attaches to the wall. The arm extends but doesn’t bend like most which I love. It was alway so clunky trying to fold or bend the other mirrors back. This is a good choice if you need a hard wired warrior!
