I got this because my goggles fogged at low speeds in high heat and humidity. I saw no difference, the fog still remained. After a few weeks of applying this stuff, the lens began to crack around the tearoff posts and where it attaches to the frame. This has not happened to any other of the same style lenses that dont have Fog Off.
Just plain did NOT work, caused blurred vision. Temp. was 34' sleeting,had to LIFT the faceshield at 60mph to get clear vision.
A good product for keeping your faceshield clear when riding in cool weather. Will keep your breath from fogging the face shield. On super-cool , foggy mornings (ie. less than 40 degrees) performance dropped off noticeably. Also, requires treating the face shield weekly. A good inexpensive product overall.
There have been no questions asked about the Fog Off Treatment.
