Would buy again.
This product is better than expected. It does help keep glasses from fogging up when wearing a mask. I work where I am going in and out of a cooler alot. Sometimes my glasses fog up when coming out of the cooler. But it is better than if I didn't use the anti fog glasses wipe. It might be hard to see but I used the anti fog cloth on one lense and a regular cleaning cloth on the other. The side I used the anti fog cloth on is definatly clearer.
