Btw, take the case off of the laser pointer and solder the resistor. The melt butter with it. But DON'T shine it in anyone's eyes, or even on their skin. It can become quite dangerous if you screw with the resistor.
Be careful many laser online store are scam.....unless you can find one to be able to proof their power. Typically a 50mW will already enough to light a match. I order a 100mw laser from lazerer.com. It comes with a sheet of power certificate of the laser.
Myself turn out 130+mW. Don't buy cheap one as 90% of them are fake.
