Waterproof 200mW Red Laser Pointer That Lights Cigarettes

I received this laser a few days ago. It is waterproof and focusable. The red laser beam is not visible during the daytime, but the laser spot is visible even at a distance of 200-300 meters. Overall, it meets my requirements.

The divergence angle of this laser is relatively small, and it can easily light a match after adjusting the focus. Even without fog, dust or smoke, the red beam can be slightly seen in dimly lit room.
