This shower mirror earned The Best rating from the Hammacher Schlemmer Institute because it provided better visibility and was more durable than any other model. The Best Shower Mirror displayed a clear reflection and allowed the least amount of fogging and condensation build-up in a 105º F steam shower. Unlike other mirrors that have to be twisted manually to change magnification, this mirror uses a precise, yet simple 1-5X zoom mechanism that provides personalized magnification at the touch of a button. Its unbreakable, polycarbonate mirror surface did not shatter or show any signs of damage after it was dropped repeatedly onto a tile floor from 5'. The mirror has the most features of all models tested, including two wall-mounting options (screws or suction cups), three LED lights that surround the rim of the mirror for up-close shaving, a razor holder, and a built-in digital clock. Requires three AA batteries. 13 1/4" H x 8 1/4" W x 3" D. (2 lbs.)
