For just about the same money this thing doesn't even touch a sig sauer romeo series or, a holosun product due to the horrible windage/elevation adjustments. I purchased 2 romeo fives off amazon for a $119, it is only a red. They are non existent!

Biggest downfall is the dot looks like a scribble, it’s oblong like a oval no where near a circle. Tore button cover off and circuit board flops. Not worth my time. Nt worth it.
