Does anyone know of a “fog free” shower mirror https://www.mistershaver.com/✪✪✪✪✪-fogless-shower-mirrors/ that really doesn’t fog up? I thought if I spent a little extra on the Sharper Image $40 model that it may actually work. Surprisingly, it lasted less than the $10 cheepie mirrors. Out of frustration, I’m willing to spend some bucks on one that works as advertised.
