Guys im pretty sure you could modify any of the chinese replica lasers to output .5mw instead of 5mw. A cheap laser diode from ebay that outputs .5mw could be replaced inside instead of the 5mw one it already comes with. It would be nice if ThunderCactus could modify such a thing with propper documentation, even go to the extent as to test it out in front of the person buying it.
