Yes, quite unconfortable indeed. And don't ever think of giving it to a kid.
It's not a toy! (for kids ;-)

For the purpose I stated in my first e-mail, I wouldn't, and not only because
normally these people doesn't like to be photographed, but also, because their
dark-blue uniform will absorb a lot of the low powered laser light (laser sights
are more powerful). At least you could try on marines  :-)  :-)

And to get back in topic... don't point it at police, don't irradiate your eyes,
but give it a try in difficult AF conditions and let me know...

Greetings,

Gerard.

BTW: Also expect weird reactions from "normal" people who're looking too much
TV.
