This laser is good. It uses two 18650 batteries, which is preferable to ones that use either one 18650 or 16340 batteries. The laser is strong, although I doubt it outputs three watts. Considering the price, it likely has a 1.6-watt laser diode. Regardless, protective glasses are essential. The laser is bright enough that even looking at the beam or the spot can damage your eyes. Absolutely do not look into it. The switch failed eventually, but the seller provided assistance. I'm pleased with their service, so I also purchased a good green laser.

The order was placed on October 22, 2020. It reached Slovakia on November 26, 2020, which was a reasonable 35 days. The product was packaged in a standard bubble wrap envelope. The laser pointer that was ordered arrived undamaged and worked perfectly. When immediately tested indoors, it lit a cigarette in a few seconds from a distance of 2 meters. This confirms its advertised high power. Communication with the seller was excellent. I highly recommend this seller to others, due to the prompt delivery and perfect working order of the product.

I appreciate it very much, I am super excited, and I wish you strong and happy holidays. This is a very strong boot, it is very powerful, it burns instantly and breaks balloons.
