I assume these are much more powerful than the little dollar one I bought my Grandson. Even that toy was surprisingly bright even at a distance.
I have a laser pointer that came with a few lenses in a nice little case.
A couple of times I burned a pinhole in some very thin plastic at a few inches.
Even with the glasses, it was still a bit uncomfortable.
It’s sat on the shelf for a couple of years.
The laser seems solid and well built but has some oddball cheapo batteries.
