Yeah, I kind of took them at their word on the goggles; my HS science teachers kind of beat into my head that even the milliwatt lasers we had (which, back then, were about the size of this one) can blind if shone directly into the eye. It stands to reason that since a 1 watt laser is 1000X more powerful, and lasers by nature concentrate all that power to a single point (which is why milliwatt lasers can damage retinas,) these should be handled with care. Still very cool though, and would TOTALLY keep the neighbors !#@#ing cat from walking on my windshield.
