it has a timer on it, and every half hour it turns off, so if someone’s going to the bathroom, they’re sitting there in the dark. I’ve called Wayfair did get back with me with a very small print that I can’t even read and I believe it says that they’re not going to exchange it. No return. Extremely dissatisfied with that result.  I really like the looks of the mirror and would either like my money back or send me a mirror without a timer.
