The author of this article makes several claims about how you can get an item remixed by the local shops and how you can skip over the marketing of a major western brand and just buy things almost fresh off the line.

I don't doubt the fact that you can by things in obscure Chinese labels claiming they are from a certain brand, we do that here in my country where mall shops will sell you "original" products that skipped over any official Samsung/Huawei/Etc. vendors. But this entirely just headphones, chargers, batteries, etc.

I'd really like to believe Shenzhen is a place where I can get an existing product remixed with any oddity I'd like but I also want to see a proof of that. Everything that these people ship out overseas to developing countries that resell their products no questions asked are selling smartphone accessories.
