Previously available only in spas or luxury hotels, the luxury of a fog-free mirror can be yours to enjoy in your own master bathroom. ClearlyYou™ Mirror Defoggers transmit gentle warmth across the mirror's surface, preventing moisture from forming while you bathe or shower. Self-adhesive backing allows easy application to any wall-hung mirror in just minutes. ClearlyYou™ Mirror Defoggers come ready to install in several shapes and sizes. Pre-attached power leads conveniently connect to your bathroom's 120V lighting fixture. The mirror defogger draws only a minimal amount of energy and operates at a constant, regulated temperature of 104 degrees. Not suitable for installation in the shower.
Great product! Does work better for new construction because of the need for power. But, I put it in an existing bathroom during a refurb.
I use it behind a shower mirror. Does not seem to take away the mist as well as I thought it would. Maybe it has to be on for a longer period of before getting in?
