Laser was a gift. Been a while since I charged it up. You can use it for 3-5 seconds continuously then you have to let it rest.I'm kinda interested in the laser you mention, more than the goggles. Fire ants are my arch nemesis now. If I can kill em' with a laser, I'm interested. As much fun as knocking over their mounds are, then spraying the shit out of them with bug killer, the satisfaction of zapping them and/or setting them on fire kinda gives me a revenge boner. Might be a fun way to kill half an hour. Hi-tech DIY pest control without chemicals.
