26: Laser Pointer really Uchitori cigarette ignition Choi Han firecrackers paper like the Internet, said that bad? That this not able to self-defense?
Laser Pointer shooting, false description.
In fact, play is also very good, there was a lot of people ask us why flashlight somewhere else that can shoot birds, you can not say that the maximum power. Advice to them is: since they promised to shoot birds, very careful, buy back Uchitori test play, not give them to go back. Such own both free play laser, do not bear the freight.

They really did that.

Laser Pointer point match is very simple, true enough 50mw power can focus after one second lit red match head.
And false descriptions are often marked must have power 5000mw power or 10000mw etc. to achieve the effect of a match point.

As firecrackers, we tested Connaught Green 200mw red laser can be focused after the lit gunpowder. That is, the lowest point firecrackers power is 200mw, just lower the distance.
If 1200mw blue firecrackers, 1-2 meters can be lit. Tests have to shoot video on the Internet, you can search for the next.

As some paper, Connaught Green 2W blue laser flashlight tested focal point of pure white A4 paper, it can be lit from the flame. But requires skill, or can only burn a hole in the paper.

As for self-defense, it is relative. Because there is such a high-power laser above the thermal efficiency, very dazzling, but also on human physical injury, there is a certain effect of self-defense.

Of course, some people even if not necessarily anti-qiang took the body, the tool is only a tool, if you really consider for self-defense, or to take into account their actual experience.

Recommend yourself to learn more about laser, if you want to play professional point.

If you want to play tens of dollars, it is simple, no need to know so deep. I like best.
