Great goggles UNTILL YOU TOUCH THE INSIDE OF THEM WITH ANYTHING. I used a microfiber cloth I used to clean my phone screen to try to clean off a bit of water to avoid a water stain. I tried to clean the right goggle, as you can see it scratched it up irreparably!! They work great and don't fog for me. 2 stars because I will be seeking a new pair in form of replacement if at all possible because this isn't acceptable. You can't expect someone to not try to maintain their equipment but ruin it as such when an attempt is made. No, it isn't just dirty it became scratched from a harmless cloth!
