It’s just ok - Gideon Optics Judge XL Reflex Red Dot Sight, 1x22.5x28mm, Green, 6 MOA dot 1x22.5x28mm Reflex Red Dot Sight

I have this on my SW 17-5 revolver. After 200+ rds: Con: dot is not precise but shows flaring and starbursting at useful intensities. Controls are awkward; not easy to use. Uses odd battery rather than the ones usually found in other red dots, and, they don’t include a cover. For a few dollars more, My vortex defender ST is a better product with none of the above faults. Pro: larger screen size.
