I'm going to to ahead and say that it isn't legit, but that's just my guess. Also,
Swiss doctors reported a case of a boy who bought a 150 mW laser, sold as a "laser pointer," which left him temporarily blind in one eye, and with 20/50 vision in the other eye, after he shined it in a mirror. The boy's vision eventually returned to near-normal. The doctors said that any laser powerful enough to burn holes in paper, light matches or pop balloons are dangerous and could cause immediate blindness.
I don't imagine you plan to look at your laser at all without losing your vision, do you?
