This product works as described. It's nice because you can take it off and put it on a different helmet.
It does take a few tries to get it exactly where you want it, it took me 3 tries over a couple of days. It was constantly in my line of sight.
Overall, I'm pleased. (Posted on 1/23/13)
I have been using the sun blocker strip for the last two weeks. The strip works to an extent. I live and ride in west Texas. The sun's glare is brutal. Riding into a 5pm sun can be daring. I was considering having an auto glass tinting store apply auto tint product to my face shield.
I had problems applying the strip to my face shield. The air bubbles were difficult to remove. Overall, I am better off with the sun blocker strip than without it. (Posted on 6/24/12)
This is a simple, good solution to riding into the sun. And since it uses no adhesive, it is easy to move from one helmet to another. I just would have preferred it if it were deeper so that it would achieve the same effect even if the shield is not fully lowered. (Posted on 5/19/12)
Why did I wait so long to get this thing?
Blocks the sun without a huge wind-grabbing visor. Keeps me from being blinded now that it is winter and the sun is always low and backlighting most every tricky corner.
Word of advise: If you plan on using on more than 1 helmet, just buy another. It can be a pain to push out ALL the air bubbles and once you get it right you really don't feel like doing it again.
As unbelievable as it sounds this thing does NOT intrude into my line of sight AT ALL even on my super compact Shoei. (Posted on 4/13/12)
It works, it's cheap, you need it. It's like wearing a baseball hat while riding, keeps that nasty low sun out of your eyes, and it doesn't block your vision. It put it inside my dark shield and now ride east in the morning commute and west in the afternoon commute home much more comfortably. Like I said, you need this. (Posted on 2/11/12)
