Works well, but brightness drops a bit at distance - ADE Advanced Optics Ultra Compact Pistol Green Laser Gun Sight

Overall I’ve had a good experience with this laser because it’s compact, easy to mount, and performs well at typical indoor or shorter distances, but I did notice that the brightness isn’t quite as strong when you stretch it out farther or in very bright conditions, which isn’t a dealbreaker but something to keep in mind depending on how you plan to use it, and aside from that, it’s been reliable and holds zero just fine.
