Nah, he'll just put his eye out!!
Odd, though, I don't see a power rating for the laser anywhere. I thought they had to post that.
I did notice that you can pre-order more than 1 - - at 5 grand a pop!!!
We have a laser etcher/cutter at the local maker space, but its wattage is too low to really use it. Won't leave a mark on bare or anodized aluminum (think magazines), barely left a mark on hard plastic (think Magpul magazines), so I can't really use it to mark up my mags or cut a decoration on a receiver, which I wanted to do. It did etch my acrylic test piece, though . . .
