To all those who hesitate to leave on a Chinese brand, I say "start you"! Personally I was a fan of Samsung (S2, S3, S5, Note 2, Note 3) I hesitated to leave for the Dual Sim, well I do not regret: it's cheaper, better finished (metal), it works as well and the autonomy is better than the rating. What more? For me the only point loss is that if you use it 2 more possible to put a micro Sd. If not completely satisfied, delivered in two days top chrono from Italy!
