About Laser Safety: it is a laser of less than 0.5 mW. It is completely safe. I quote the British equivalent of the National Health Authority, concerning laser of less than 1 mW: "No injuries have been reported to this power." (See wikipedia page "Laser pointer" sorry, I do not find any equivalent information in French ...). He can dazzle (do not aim for a motorist with) but the eye closing reflex prevents permanent retinal damage.
So do not let that scare you, as one of the commentators, the "Danger" label. And do your own research if you really want to be sure. (Small funny detail, the label indicates "light is emitted from this side," but the arrow is pointing in the wrong direction, toward the carabiner key chain It's not a one-time error, as the photo. amazon up the label in the same bad place)
