Good for a fixed 4x scope! Works decent in low light, great in bright light. All crosshars, hashmarks and chevron are visible when illumination strip on top is blocked. Clarity is above its value for sure. I have used real Trijicons ACOGs before and this is not a bad replica. Not as clear but its a pretty close copy! Holds accuracy well. Was able to get zeroed qithin 5 shots and has held for several range trips with no issues. Be sure to recheck all screws etc before and after shooting.If I had only 1 issue it would be with focus clarity when wearing any prescription eyewear. The two sides of the crosshairs are not equally focused when viewed with or without glasses. Hard to explain but the left side is out of focus with glasses on and the the right side will be out of focus with them off. I know its a distance issue regarding wearing prescription eye wear / contact, but none of my other scopes have the same issue. More of an annoyance than a serious issue.I am debating ordering another as It works very well as a low budget 4x scope.
