Purchased this product as a gift for my son in the Pacific Northwest. This product works when no others have. Customer service was needed for a shipping error made on my part. I must say the issue was handled quickly and courteously. Will order more products. Thank you!

I was sent the wrong items at first, but the company quickly sent me the correct order without any fuss or complications. Item works great to clean glasses and screens.

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.

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.
