good for basic use but doesn't hold up
So I purchased these a few weeks ago to help prevent my glasses from fogging up when I wear a mask. Application is tricky. if you wipe the glasses for too long with the wipe, you end up removing the coating. Once you figure out the perfect application technique to coat you glasses, you must be careful when cleaning your glasses in between applications because you could wipe off the film. I tried this product the other day before going outside in the snow, and the wet flakes must've washed the coating off within 2 minutes. all in all its worth it because it IS better than nothing, but if there's going to be precipitation proceed with caution and make sure to always carry extra wipes because the film doesn't last too long.
