Description
Instruction:
A cheap 10mw green laser pointer pen is a small laser designed to highlight something of interest by projecting a small bright spot of colored light onto it. The laser beam is not in itself visible from the side, but is visible as a result of light scattered by dust particles along the beam path. The small width of the beam and low power of typical laser pointers make the beam itself invisible in a reasonably clean atmosphere, showing a point of light when striking an opaque surface. Some higher powered laser pointers are faintly visible via Rayleigh scattering when viewed from the side in moderately to dimly lit conditions.

For $12, it’s a steal. Replacing the battery locally would cost around $10. Everything works except for two things: 1. The alarm is hard to hear, and 2. Setting the alarm is a bit tricky.

So happy, thanks!
