It just died today actually. I have really bad luck with lasers. It only lived exactly 1 week too.
It doesn't make sense, I just shut off a street light, then clicked it off. Then clicked it on again at my parked car and the dot was huge, like it was unfocused, so I turned it on and looked at the focusing head, but it was in the correct position.. I turned it on again and it flickered and turned off. I assumed it was just the battery, but after changing 3 different batteries it wouldn't turn on. It's dead again!
It was ran at 190mA, a very reasonable current for a 6x GGW. It also never really heated up, I could use it for 2 minutes (never went longer) and it would stay regular temperature.
Kinda rare (here at least). Your best bet would be a smoke shop, dollar store, truck stop gas station, etc. Anywhere that has a large selection of tobacco products. Even then I can't guarantee anything
