High-End and Powerful Blue Laser Pointer 473nm / 465nm / 445nm

I did some burning tests with this powerful laser. The laser beam went through white printer paper easily from a distance of 10 feet. Also, it can etch wood and leave burned marks effortlessly.

The laser worked fine and was as described. However, the pair of safety glasses in the package were broken.

I bought the 1.8W version. It can burn through a red solo cup in seconds and then leave a mark on the wall. I will be buying one more of the 7W version soon.
