Rating: Works well but not perfect.

Anti fog is a hit or miss proposition with the user making most of the errors. I routinley wash my mask with a gentle toothpaste and then apply this anti fog before I dive. For some reason my right lense always tends to fog up anyway but it goes away after a few times. I think the mask may be to blame or the way I apply the anti fog. If that is so, then this is a great solution becaseu the left side of my mask stays perfect for the whole dive. Apply carefully and Im sure this anti fog is as good as any other product.
Rating: It works

I like all of the McNett products. I tried this spray and I think that Spit spay works a little better but the difference is pretty insignificant.
My personal opinion is that no anti-fog really works for more than one dive and if it works well for that one dive its OK in my book.
