Super Powerful Handheld 15W Blue Laser Pointer with Batteries

I was invited to review this product after using it for two years. I was impressed by its high power. However, the beam divergence angle is relatively large.

What I don't understand is why a 15W laser pointer is equipped with OD3 safety goggles. The accessories should be improved.

This blue laser is really powerful! Its laser beam is clearly visible even in the sun.
The heat dissipation system is excellent, and there is no problem using it continuously for several minutes.
