Laser has two sets of Lito-Ion batteries and two chargers.
Comes with a stand for steady use.
Never point laser at any living creature. Store laser with batteries taken out of unit. Batteries go in intuitively backwards, so it if doesn't work, flip the batteries. Never store batteries in the charger. Charge time is about 4 hours. Laser burns when aimed at items. The darker, the better it burns. The closer the better it burns. The more steady you are, the better. Recommended all participants around laser wear dark red colored glasses (not included). Direct eye contact can cause serious injury. Contact on skin will cause burns.
