I have digging around the net trying to find information. I know that this is often inaccurate, but I have read that some cheap imports do not have a filter to protect your vision.
IR? Going with what I have been reading.
Obviously we are not going to be pointing these lasers in peoples faces but some sites seem to imply that there is a problem even without this happening.
Either way it is quite legal to import the parts and build your own. As long as it is done well and handled properly the risk should be eliminated.
