The Price But it is really not that bad for how long it lasts.
The last reviewer must have bought this stuff to use as a cleaner, they did not read the directions, put it on the outside of the lense, something because it holds the fog off great. You Spray a light mist on the INSIDE and then let is haze, buff it off with a small soft cloth.
Good stuff if you use it right, but if you are looking to clean your lense, water and a mild detergent works great, it is does not affect the lense like Windex. Read the directions and use it for its intened purpose.
