I have several issues with the sight. The first I received had a short in the circuitry and had to be removed. OpticsPlanet quickly turned around the replacement. The replacement image is not totally crisp. It was quick to zero, and held its zero through about 900 rounds of 9mm at a tactical course this past weekend. Two major problems surfaced. When moving and shooting fast, the sight was hard to acquire. Second and a major issues was that rain drops on the lens obliterate the triangle. It turned into a large irregular blob. Not good in a tactical environment.
Pros: Fairly easy to install once rear sight removed. Easy to zero
Cons: It is hard to acquire the triangle when shooting and moving. The biggest issue is shooting in the rain. Rain drops totally distort the dot image.
