Review (3/5): Ok, but not totally anti-fog
UPDATE - keeping the mirror clean an fog free has proved to be difficult. Knocking back a star.
Seems like it sticks up quite brilliantly. Hope it stays. The plastic mirror exposed is more like 5.25"x5.1" in size. Fogged up first time I used, but was clear after splashing water on it and keeping it wet.
Besides the fogging issue, I wish it were bigger in size. Otherwise good little stick on shower mirror.
