I bought there ca 8 months in Vietnam and I can tell you it is the best Loint androphone that I could use.
Everything works perfectly.
Small weak point for the battery can be holding one day in forced use (use of GPS for 3 h + music + deezer game, SMS ...).
For this price I think it's hard to top (buy 120 euros in Vietnam).
And for all those who receive the Chinese version, if you want you can find a discussion of frandroid explains the way to pass the international release (for all Google services).
Do not ruin by paying an S ..... it is just as well be even better: D (personal point of view ...).
