I bought 2 of these BR pens about 3 weeks ago. They are my first 405nm lasers and I think they are very cool. But I'm not sure mine is up to spec with a lot of other peoples lasers on here. It is bright (cosidering what color it is). The main thing i see on here is people being able to see the beam. I can barely see it at night. And indoors when its dark i can see it. I can see it a little when its light out, but only when its smoky. And it doesn't get warm at all on any body part.
Its still a really cool laser, and i plan on keeping it. It guess others' reviews made it out to be more powerful.
Because 405nm is on the edge of UV, everyone's eyes act differently to seeing it. Even high power Blu-Rays cant hardly be seen by some people. Go outside in fog, or high pollen, and you should see the beam clearly.
