And for anyone considering a purchase, be careful. Every laser is dangerous when shined towards your eye, but high powered lasers like this can quite literally cause permanent blindness even when reflecting off walls and carpet (and we're talking milliseconds of exposure, not prolonged viewing). A lot of people think they're fine as long as they don't make contact with the beam, but that's definitely not enough; you NEED the safety goggles. These things are no joke.
