They look great, thats a given. All Dyes stuff recently does.
But they are totally unwearable if u wear glasses (like me), plus a lot of people dont like the fact that the lense is soo close to their faces. I dont think the chin coverage is that good on them as well.
Changing lenses in them is a particualr pain in the arse, much worse than the (fairly easy i think these days) JT Spectra.
Try before you buy is the lesson with em, then again that lesson is aplicable to pretty much everything in paintball. Personally, i'll stick with my Flex 7s.
