When my wife and I first began using these last fall, they worked well. This summer we both found ourselves squinting more and more in bright sun. When I checked our shields I realized they were barely changing color any more. The anti-fog properties remain intact but the photo-sensitivity is no longer useful. An Aerostich rep suggested I talk to the manufacturer. I left a message but nobody called back. (Posted on 9/22/09)
Not as good as I thought it would be. Because most modern face shields block some portion of UV, it does not get as dark as advertised. And, at night it creates double images and glare. I was expecting to buy a product that would allow me to use a single shield - morning, noon and night - this ain't it.
