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.

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.
