Tips for purchasing 500mW laser pointers
The 500mW+ laser is classified as class 4. Laser pointers of this power range are uncommon in the market, which can quickly light cigarettes and matches. Generally, class 4 laser pointers are handheld style (for pen-type lasers, the maximum power we can reach is only about 400mW). We adopt an internal cooling system and PCB protections for high-power laser pointers to improve safety and durability.

Precautions for use
① Do not use a 500mW laser pointer to point at the aircraft.
② Do not use a powerful laser to point at reflectors.
③ Please wear laser protection glasses, and never let the laser beam enter the eyes.
④ Make sure the battery is inserted correctly.
⑤ Do not make the laser pointer work continuously for more than two minutes, or the service life will be affected.
⑥ Please do not disassemble the laser pointer or accessories. Any problems caused by this will not be our responsibility.
⑦ Please keep the 500mW laser pointer away from children, which is not a toy!
⑧ We assume no responsibility for intentional injuries.
