Visiting China last year, I was browsing in some stores and found a whole range of phones that caters for the domestic Chinese market.
Now I'm starting to see some of those appear online (Vivo, JiaYu, THL etc) and some of them are getting favourable reviews.
Their specs and prices are pretty good.
e.g. Quad-core A9 1.2Ghz, 5" 720p screen, dual-sim for around NZ$300.
Looking at buying options you could either go down the eBay route or an online store like Pandawill or Fastcardtech. You don't have to look far to see people grumbling about them sending them older versions of the phone, different phones altogether or generally being stuffed around.
Question is, which of these sellers (online store or eBay) that people had good experience with. And which ones do you think to clear steer of?
