Works most of the time
Yesterday after about 8 uses, the Nerdwax failed. My goggles were cloudy almost immediately after entering the water. It's easy to use and perhaps I didn't do it right, although I did it exactly as I had all the other times. I'll try again.

Great product for someone who need glasses all day.
It is so great for days with high humidity and you are in an airconditioned environment. My glasses don't fog up.
