The Chinese love to troll the stupid.

[Alaskan]

When I first became interested in green laser pointers I too found those 10 watt Chinese laser pointers, so they claimed. Came here and asked about them, received the same answer, their specifications are BS! I contacted the seller and they admitted the unit wasn't really 10 watts, but said it was very powerful. I think what they depend upon is that few buyers have laser power meters, or just suck it in when ripped off. Aliexpress has lots of sellers who as a matter of routine lie about the ratings of the laser pointers they sell.
