Used if for my snowboarding goggles and my motorcycle helmet and it worked great. It has held up for a week after one application for my motorcycle in cold weather. Will continue to monitor but I'm satisfied

Used it on a motorcycle helmet for snowblowing. It wasn't perfect, but it greatly increased visibility.

This actually works pretty well (better than anything I have previously tried). Make sure to not over buff, or it may be rubbed off. Worked solidly for about 4 hours. Seller was very good

This product really works on glasses. Our whole family uses it.

LIKE WORKS WELL

Buy some basic toothpaste, just a tube of it, a small one if you’re traveling. Doing that lasted me the entire snorkel outing and then reapply. Make sure there’s no sand in your mask as not to scratch.This stuff lasted all of the amount of time it took me to put my mask on and enter the water. Like a minute or two before it started fogging up. Totally useless. The toothpaste was awesome and figured it out with 4 days of our snorkeling trip left.As Maui says “your welcome!”

I am pleasantly surprised that this really works with mask wearing! It also keeps my glasses cleaner so I don't need to clean them as often.

Really keeps fog at bay on my glasses and bike rear view mirror. Highly recommend
