The Real Deal
Wearing a mask makes my glasses fog up. I tried getting anti fog from a ski shop, but It sucked.  This product actually works as advertised.  I can finally wear a mask, or wear a mask with a face shield, and actually see.  Game changer.  Love this product.  Also, it was the least expensive of the anti fog products offered by AMAZON.  What are the chances?
