Im somewhat new to lasers, but my first laser was a 5mw green laser gift from a friend so I have no experience buying them. I mainly want something i can easily carry around and be bright, and impress other friends, and maybe burn small stuff.. All of these lasers are 100mw & i don't know how to tell which one is the superior one. What exactly is wide beam? Does wide beam weaken the distance or intensity of the laser? Also, will I be getting what I payed for from o-like?

I'm pretty new to lasers myself but I think the prices show it all, the more expensive the laser; the better it is. I mean this in-terms of buying from O-like, not comparing different companies. The wider the beam, the less intense = worse for burning.

This is just want I think, you'll probably want to wait for some more experienced lasereers to post. Also, remember to buy safety goggles if you haven't already!

Thanks,
Gun

I think the Power Rock will get you the best bang for the buck in this group.
The Wand looks interesting due to having a larger beam diameter at the aperture.
Maybe it works a little like a beam expander?
