I have a Chinese SD2SNES that so far has not given me any issues, but that does not mean all Chinese units are perfect. I consider myself lucky. The thing with them is that Quality Control is all over the place, and there would be no one to complain in case (not even here) you get a dud. In order to get one of these, you must bear this in mind.
We know KRIKzz's quality control and customer service is honestly second to none. If my country wouldn't tax me 60% over imported goods I would certainly grab one from him instead of rolling the dice with the Chinese one, and I still plan on getting an original one now that my brother lives in Canada and will visit regularly.
It is also worth noting that the SD2SNES is a grey area when it comes to its morality, as it is open source, but Everdrive clones aren't. KRIKzz keeps his source code closed for a reason, and we should respect that.
EDIT: oh, v07 is working beautifully too, but I have not tested the previous versions
