I don't get all the troubles everyone has with Laserworld. They are in fact measuring their lasers with Swiss Watts. Nowadays 500 Swiss mW are actually 2000 (normal) mWatts, but I have to check the circulation rate. The Swiss Watts are losing their value, maybe the numbers aren't correct.
Ok, I'm sorry about my low humour level.
But, IN MY OPINION, Laserworld has some serious problems with his sellers. As I read here, Laserworld was a very good reputated company that sells products with the right specs on it (didn't they, White-light/RGBLaserFan?). Their e-baysellers on the other hand, sell their products with underrated specs. Laserworld reads all the bad replies and send "Peter", who doesn't get any clue of the bad comments. Now, search the fault in this last alinea.
