I've had mine for over a month. Really great laser.
Treat it like a firearm and DON'T pass it around. It will pop a red balloon at arm's length in a heartbeat. It will do all the other stuff too.
I agree with Hemlock on the "don't pass it around" part.....a friend of mine twisted the crap out of one of my lasers - thinking to "focus" the beam that way, and busted it beyond repair...it was my first version of a flashlight mod for the high power red pointer....*sob* *sniff-sniff* Uhm, yeah -(thanks for the tissue) anyways - don't hand it to anyone you know cannot pay for it !
