You also need to be able to speak Chinglish, as there is no such thing as a green violet laser. They often misspeak when describing items for sale. It is likely a 405nm violet laser with the output power somewhere between 50 mW and maybe 100 mW.
So, while the seller clearly doesn't really know what they're selling, the actual product exceeded my expectations.
I can understand the skepticism on its output, but as the pointer has a more honest label stating "< 200 mW output", and it is noticeably brighter than the comparably priced 405nm laser 301. I'm going to stand by my "eyeballing" opinion that it is emitting at least about 150 mW, until such time that someone tests the laser with a LPM and proves me wrong, and if you do, I'll send you my hat, it's a very-very nice hat by the way.
Anyone willing to take the bet?
