Sanwu 304 lasers

So I wanna buy a Sanqu 304 laser but I have some questions about the lasers.

https://www.sanwulasers.org/product/304green

The 100/150/200mw-s are guaranteed?
And the pictures there are many different size of the 304.. which is the green/blue/red?

Sorry for my English, and thanks for your answers.
