Hey everyone i have been using this electronic tint shield on my helmet and this thing is to cool and i wanted to share my experience with. First you place it on the inside of your shield then charge it up then with one push of the button it automatically darks the shield push it again and instantly becomes clear again. This thing works! The best part about it is it won't fog up on you because its sealed around the edges. check it out at Tricplate.com they have videos.
