Things I liked: Everything seems fine. It looks as if it is a very well made light for the money.
Things I would have changed: Nothing yet.
What others should know: I am mounting it on a 12-gauge shotgun. Although it appears sturdy enough to handle the vibration and recoil force, I won't know until I've fired the gun at the range with the light on it.
Things I liked: The way they fit
Things I would have changed: Nothing, though I would pay more for a polarized pair.
What others should know: Great value!
