Great laser sight! - LaserLyte VRail Mount Laser Subcompact V3 FSL-3

NOTE to Unhappy - I have purchased several of these sights. Most of them are easy to adjust and work great right off the bat. However, two of the sights I bought were very difficult to zero in. The screws moved "out" very easily but would not move "in" unless I put a tremendous amount of torque on the little Allen wrench. Don't be afraid of breaking the wrench! Just apply steady, even pressure and it will turn (eventually). Once you get past the "rough spot", the sight is very easy to adjust and the problem disappears forever. BTW - the batteries probably did not "die" after 5 minutes, that was the auto shut off feature.. RTFM!
Pros: Battery saving feature (blinking light)
Cons: Sometimes "excessive force" is required to zero in
