I can tell you they do rip each other off even if they are not all the same company. I will no longer work with Chinese manufacturers at any degree. It is incomprehensible the sheer amount of work they go though to steal IP. Even if it is to make 1% or 2% profit. It is like they can not think for themselves. If they could they would make so much more profit.

Now… Where is my AceBeam X65 Mini at? lol.
