I've found a few sites, but the price for them seems unbelievable, specially coming from t-mart and dhgate. for example

Can this be right. I also found a green laser 300 mw for 62 bucks at T-mart.

I'm looking for a blue laser that has a visible beam. Any suggestions? (same goes for green)

also is kai domain true to their specs?

Thanks in advance

That's not a blue laser, it's a violet/purple laser (405). It may or may not be 200mW, but even if it is, the beam of a 200mW 405nm laser is nowhere near visible in normal conditions.

If that is the same one of deals extreme, apparently it is only 90mW.

Ah ok thx, I wasnt aware of the "nm." So is a visible beam for blue somewhere in the 500 mw area? And is that the same for green?

And yea, I'm guessing for 31 bucks it probably is not 200 mW.
