This product works exactly like it's supposed to work -- an amazing concept in today's marketplace! The unit is easy to attach to the shower wall and does actually stay FOG-FREE for my entire shower. I love that the mirror is adjustable too. Since I first discovered shaving in the shower many years ago, I'll bet I have tried 10+ different types of shower shaving mirrors, and the ToiletTree Fogless Shower Mirror is undoubtedly the best!
