Maybe the extreme heat we've been having, but I found these fogged up / condensation on every occasion, even when using anti-fog spray. From a protection point of view they are extremely good and took several direct hits to the lens without any problems.
Going to score them a one I'm afraid, if you can't see through them they aren't much use.

Good build quality overall, and a recognised level of protection (EN/BS regs or something) from a leading brand.
Without the strap, they do not sit well, and slide around a fair bit. The strap keeps them very snug. Only issue with this is that they steam up and fog quickly, and stay like that. I've tried all manner of anti fog stuff, even the stuff I use on my motorbike visors when its -5 C, and it made little or no difference.
As I was about to throw these in the bin, I found out that the foam outer padding can be removed simply by gently pulling the grey outer off. If your not wearing a shemagh or similar over your mouth/nose, then you have solved the steamage issues.
Saved from the bin!
Why spend £60+ on a set which aren't tested or rated, when you can get these?
