Average laser for the price. - Barska Tactical 5mW Green Laser Sight w/ Picatinny Rail Ring

The laser was very easy to install and setup, the only problems that I have had is the Velcro not sticking but this is easy to replace, also I have had to replace the battery a little more often than I would think it should so there may be a slight drian when not in use.
Pros: Easy setup and calibration, bright laser
Cons: Velcro for switch does not stay attached, battery seems to drain quickly,
