The Laser I had receive took longer than a month to arrive, but the laser that arrived was much more powerful than what I had thought. It was instantly burning plastic and seering wood.
Just a split second of a reflection of this laser burned my leg, which had symptoms similar to heavy sunburn.
The Laser is not a dot, but more of a short line. Also diverges a lot at range.
I tested in the lab, this laser actual output power is above 1000mW, double of the rating power on the website. I guess they might have sent me the 1 watt model: https://www.c4lasers.com/home/8-lark-1w-blue-laser-pointer-1000mw-450nm-high-power-class-4-laser.html
I am more than satisfied with buying the 1 watt laser at an 'education price'.
