Ok, but not totally anti-fog [SEP] UPDATE - keeping the mirror clean an fog free has proved to be difficult. Knocking back a star.<br />Seems like it sticks up quite brilliantly.  Hope it stays.  The plastic mirror exposed is more like 5.25&#34;x5.1&#34; in size.  Fogged up first time I used, but was clear after splashing water on it and keeping it wet.<br /><br />Besides the fogging issue, I wish it were bigger in size.  Otherwise good little stick on shower mirror.
