It scares the hell out of me as these kids are posting on youtube the power in these things, i.e. bursting balloons, igniting matches, cutting different materials. Whats even worse is this company are carrying on creating more powerful lasers
, at the moment they have blue lasers, powers of these lasers are from 1000mW to 7000mW. The prices for 457nm lasers are not low but they are battery powered hand held.
