I wish the pressure switch it comes with was a on/off switch. It requires way to much pressure to sit with it on for a extended period of time. I also wish the adjustible scope mount was of better quality. It's loose and doesn't keep the light steady. It loses its center way to easily requiering to frequent adjustments. I bough a after market mount for a different system and it works great now.
I read complaints about animals being able to see the laser even though it's advertised they can't. I have two labs and a Bull Mastiff. They all like to chase the red laser. Only 1 of my labs can see the green laser. She chases it all around and the other to try to figure out what she's so excited about and chasing after. The wild animals I have spotted with it (deer,raccoon,opposum)didn't run from it. It seemed like some noticed something because they looked right at me. That could have been noise I was making or smell. Non of them ran. They went back to walking or eating.
You can easily adjust the beam to fit the field of view from your scope. I have been able to look along a tree line and clearly see everything from over 600 yards away. Overall I think this is a great product. It gives you a very versitle "night vision" system.
Pros: Works great. It really makes animals eyes stand out.
Cons: High humidity cuts down the range a lot.
