Extra-foggy.
Not even remotely anti-fog.  Foggiest shower mirror I've ever used.  It adheres to my shower wall just fine (like all Tooletries products have for me), and the size and design is nice.  But it's ridiculous how much and how quickly it fogs.  Right from day 1, out of the box.  Instructions say to avoid getting water on it, but it made no difference.  In fact, the only way to use it it is to spray it with the showerhead every 30 seconds or so.  If you breathe on it, it will instantly fog.  Not conducive to safe shaving.  I should have returned it within the 1 month window.  Not sure what I'll do with it now, probably throw it away.  After a month I even treated it with McNett anti-fog Op Drops, but it doesn't help.  I love the other Tooletries products, but this one is a big disappointment.
