Review (2/5): The sad thing is
This mirror doesn't work on batteries. I tried two different mirrors, and both were defective. The sad thing is, it is a great mirror. I love the three settings, and I love that it has two sides, one of which is a 10X. I returned the first mirror. The second works when it is plugged in, but it feels like a rip-off to pay for something that doesn't work as it should. When on batteries, it will turn on, but it won't change settings and it won't turn off, making it useless. The cord makes it cumbersome unless you have an extra place to plug it in that is out of the way/hidden. In summary, if you are willing to only use the mirror with the plug, if you wil be very happy. If you are counting on the battery option, don't even consider this mirror, as it doesn't work.
