I have had this for about 2 years now and its great!
Uses double A batteries
Comes with pressure switch attachment peace and the corded pressure switch
3 different lazer modes
2 different LED light modes(Good amount of light enough for clearing small dark rooms)
Both Laser and LED flash light have casing around them ( where it protrudes) so that when in use it cannot be seen from other angles where the enemies might see it shined from when the laser or flash light are on.
Maybe a bit pricey but considering you get a great laser that uses double A batteries, has a powerful white LED, different modes for the laser and flash light, two different pressure switches......................... Its a great deal.
