The product works as advertised. used it snorkeling in Maui with water temps of around 70-75 degrees with no fogging up. The only drawback is applying a small amount since it is in a gel form...the trick is to squeeze out a bit on your finger then rub inside the mask. Does not take much. 4 stars

This product worked well. However, you need to rinse out your goggles after applying..... You don't have to with spit. 4 stars

AquaSeal Sea Gold Mask Anti-Fog Gel is the standard for anti-fogging for SCUBA diving. Ordinary spit will work as well, but for less than $5.00, this little bottle will last an easy 25-30 dives. Doesn't sting your eyes either. Well worth the cost and if you lose it, you're not out much. Great product! 5 stars

It works fine, it's just to hard to get a little bit out of the squeeze bottle so I'm going to run through it way to quick! 3 stars

I dont feel that the product worked. We were with friends who used the tried and true method of spitting to their goggles/lens and it worked better than the aquaseal gel. I followed the directions on the bottle for the three masks that we were using but it only made a very small difference. When I purchased the aquaseal with other items that I was purchasing I didnt realize that it was being shipped separetly with a separate shipping cost so the little bottle ended up costing me $11 and change. Not worth it. 1 star
