I recently bought a laser 301 with a 3000mAh Ultrafire battery coming with it. I notice some problems.
First of all: the dot this laser produces seems to be irregular instead of round. This is especially the case when out of focus. Does this mean the cristal is broken? Or maybe it is the lens...
I found this site while researching the specifics on constructing a burning laser based on the tutorial put out titled Burning Laser Hack. I'm certain that you are all familiar with it and I want one and I want to do it right.
I primarily hang out at gun related sites (I moderate on one too)...
