I have searched for something that will prevent my glasses from fogging while I have my mask on. This lightweight piece is THE answer. My only concern was whether or not it would stay in place without falling out since it has no adhesive. I’ve not had an issue. I bought some plastic pieces to help with that and I will not be using them again.
What a relief to walk and breathe, wearing a face mask, without fogging my glasses! It seems to be lightweight and easy to carry, interesting design, I am looking forward to wearing it on a rainy day. The quality is good! The other good thing is it prevents the mask from sticking to your mouth when you talk.
I used it when I encountered heavy rain in Manhattan last week. I put it on and walk out of the subway station. Works perfectly. Easy to set up and clean. A great product to keep in the bag for when you need them. Very well made. Overall, this a great product. I would buy more shortly.
