Overpriced pointer w/o weapon utility - Beamshot GreenBeam 2000 Daylight Laser Sight

I've messed with this product for about a year and a half now and have been through several batteries. I've tried both the picatinny rail mount and barrel mount on several ARs and AKs to no avail. The closest I can get the dot to point of impact at 15 yards is about 18 inches. If you're shooting across the bedroom at 3 yards maybe its 7-9 inches off. It wont point straight no matter where or how I mount it or on which gun. The green laser might be brighter but the battery life is shorter than red. Plus green is not as reliable in colder weather. Green visibility is superior when it works. The pressure switch requires southern ingenuity to mount and hefty deliberation to activate. The switch is too small and too awkward to mount. This is just an overpriced laser pointer, not a weapon sight.
Pros: bright day visible green laser
Cons: useless as a weapon sight
