Review on 🤓 Nerdwax FogBlock: Prevents Fogging on Glasses - 3 Pack by Edgar Vasquez

This only works slightly when moving from colder to warmer temperatures. I was hoping to use it in colder temperatures but seems to have been made for those living in warmer climates. When I'm back outside in the cold and breathing with a mask, it disrupts the cold temperatures and creates a whole new layer of fog that makes it impossible to see anything. I will only use it when I'm going straight into a building from my car but can't use it for the outdoor use I intended to use it for. They were able to get my money back but it took me a long time to convince and contact someone to get an answer.
