Review on Mirror On A Rope Reflect Shower Mirror - Medium Sized, Shatterproof. Eliminate Fog & Shadows. With Stainless Steel Hooks & Adjustable Rope. by Gary Davis

I like that it is easy to put on a rope in the shower for a few seconds, which will prevent fogging in a few minutes. It would be great if they knew how to just not fog it up! Well made, the rope is easy to adjust. The included hook is functional. I don't recommend putting it on the shower head itself as the running water makes it difficult to see what you are shaving. Dropped once, no damage. That was on a stone tile, so it's pretty solid. I recommend using rain-x to make it run faster, but it's probably not necessary.
