I am very pleased with this product. It does what it is advertised to do. I can now do my shopping without having to remove my glasses to be able to see.
This is the answer for fogging problems on all types of optics!!
I have used the fogblocker on my glasses and put my mask on and they didn't fog up, I am so pleased. thanks
Works really well! Wish it was in a reusable package. I put it in a baggie after 1 use as I feel there is enough product for a second use! Thanks!
