Powerful Stainless Steel Red Laser Pointer 300mW

The specs match exactly what was described. The red beam is stable. The heat dissipation efficiency is good, and there is no obvious heat after continuous use. It's also focus-adjustable so that you can change the dot size easily.

This thing is really powerful and I can use it to burn a firework fuse. But, its red laser beam is not visible in sunlight.
