We inherited this medicine cabinet when we purchased our apartment - it had been installed in preparation for the sale, so was practically brand new.  Here we are about 3 months later, and both of the lights have failed (one within a week of the other).  Based on the other reviews, we would have never purchased this on our own, and will be looking elsewhere to replace it now.  As an architect, I'm also going to start steering clients clear of this model.
