Anybody uses cameras from YI Technology?

They have action cameras, mirrorless cameras, and other cameras that I don't know of. Has anybody tried these? They have great reviews for the action camera, but for the mirrorless camera, I heard mixed thoughts about it. If you have one, let me know and if it is okay to post some of your shots, that would be great. I want to see how you guys get great shots using this camera with stock lenses.
