Working great so far!

Got this for hubby as a gift. He's constantly been annoyed about entering the house in the winter and his glasses getting instantly foggy. This has been helpful! He's only used it once and it's working well.

Awesome! And for snorkeling, too!

I love these cloths! We use them for so many outdoor activities, but we are especially grateful to have them for winter sailing and tropical snorkeling. We live part of the year on a sailboat, so I buy multiple at a time. I always make sure to have extras on board for visiting friends to use, especially on their snorkel masks. I've found that once they use a Fog Block cloth, they want one; the extra cloths are so I can give them away as their "free gift with visit" souvenir.

Great product. Cleans glasses and stops them fogging up. You do have to use it regular but it works.

Hope was shattered

Where do I begin? So many different anti fog products used and was hoping this would be the one to work but sadly it failed as well.
I’ll admit I really like the packaging. It’s crisp, clean, easy to read and to the point. I had high hopes for it to work on my husband’s glasses but sadly it didn’t happen. I cleaned his glasses with the miracle drops then proceeded to use the cloth as directed.
The next morning when my husband left for work on the motorcycle, by the time he was at the end of the driveway his glasses were already fogging up.

I truly hate giving a bad review but unfortunately due to the price I paid for the products, I feel others should know my husband had a bad experience with it. It may work great for others but just didn’t for him.

Hey there - Sorry to hear you weren't happy with the product. For anti-fog products I would suggest applying fairly soon before you are planning to be in a 'fogging' situation, so perhaps applying before he heads out on the bike might help. Also, you'll want to make sure none of the cleaning solution is on the lenses when using anti-fog, as the cleaning solution will actually work against the anti-fog, essentially removing it. Outside of those two tips, if you just don't love what you ordered let us know and we'll work out an exchange or refund for ya :)
