Things I liked:Red and Green Dots. The feel of the sight feels solid - no movement once mounted on the rifle. Looks good mounted on my AR.
Things I would have changed:More than 2 brightness settings for the red or green dot. 2 is too few. 4 for each one would be acceptable. Even at the lowest setting, it was plenty bright for the daytime - I would venture a guess at night it might be unacceptable.
What others should know:The batteries are small - easily lost if you should happen to drop one in the grass. Don't know how long they will last, haven't had a chance to use it long enough to find out.
