Very powerful. Beam is visible at night. I did not take the beam picture below, but that is what it really looks like. Come by at night to play with it. I would love to show it off. Guarantee to impress.

Everybody has red laser pointers (650 nm wavelength), but few people have green ones (532 nm wavelength). Green is the color the eye is most sensitive too hence it's so much brighter than a red laser.

The laser has a nice black rubber coating on the outside. Comes with box and batteries. Got it as a gift and I have too many gadgets. $50 or obo.
