Top Product, Price - Well ...

Front path: my expectations were exceeded!
Good contrast even in poor lighting conditions, every ski and snowboard driver knows the problem. The tinted Flex disc clipped by a magnet, and the sunglasses is attending. This should necessarily agree but even in poor visibility, otherwise the contrast enhancement is not really effective! The good thing about the matter: the disc fits into any pocket and takes up any space. Also position the magnets and keeping the "sun disc" very good. I feel positive that the broad band bomb stuck on the helmet and does not move. With my glasses joins precisely to the helmet, so that no cold air flows to the front. (Hence a star deduction) Nevertheless, I feel the price is exaggerated. Overall rating: Recommended!
Conclusion:
+ Very good view (contrast enhancement & panoramic view)
+ Tinted windows thin and flexible, well accommodate
+ Strong magnets positioned well Flex disc, even with ski gloves easy and fast attachment seconds
+ Anti-slip tape
