So I ordered this laser a few weeks ago:
100mw 532nm Green Laser Pointer Pen | Virtual Village - UK
It arrived today and in the box was the pen and a battery, no instructions or anything. I opened up the back, put the battery in, switched it on - nothing. Changed the battery around, still nothing.
I'm gonna try and find some fresh batteries somewhere (CR123A) but until then, any ideas? :S
