Nothing to say so invents a meaningless silly anything apparently, from the many nonsense posts wasting bandwidth and peoples time looking.
Just posts to post, evidently, not for any other reason then he wonders why he has zero reps/so many negative reps?? lol
I have to ask:
What do you do with such a powerful handheld laser?
If you use it indoors, you'll scorch anything the beam touches within a 10 meter radius, you can't admire the color without the filter of protective eyewear, and you can't show it off to friends unless you buy extra eyewear.
The main problem I see is that the radius within which you can start fires is much too small and people from the next town over won't be able to see the beam on the mountainside because the beam width will be too large. The secondary problem is that if you have to buy spare eyewear for friends, they probably aren't into lasers.
