I had high hopes for this. While it does work, I couldn't use it. I had to rinse the mask so much that it washed out all the spray and the mask would fog. My husband was able to use it if he was careful to spray just a little, wipe it around and then dunk the mask in water once. But for me, it made my eyes sting a lot and was very uncomfortable. I'm not usually sensitive to sprays and such, so it was surprising. However, there's an even better idea than this. We took a snorkeling and scuba diving lesson in the pool at the hotel in Hawaii. The guy running it suggested we use his "no rinse defogger". He sprayed it in the mask, then said to swish it around in the mask, then pour out the extra. Do not rinse (which I did without thinking after using the Spit stuff and had to restart). Just put the mask on. Viola, no fogging. Worked even better than the spit stuff not including the stinging eyes. Then on the snorkeling tour, the people who run at least two snorkeling tours a day, 7 days a week had the same no rinse defogger. I finally asked what it was - baby shampoo mixed with water! It was awesome. I'm definitely getting a little spray bottle and putting baby shampoo and water in it. This worked really really well. The only disadvantage is you have to reapply. But we had to do that with the spit stuff, too. And this stuff is cheaper and easier to use. So in short, get some baby shampoo instead and skip this. The pros don't use this stuff anyway. I mean, really, if the people who go snorkeling and scuba diving every day in Maui, HI haven't even heard of this quick spit spray stuff before (none had, I asked), then it can't be but so good.
