I bought Concuest s9. At first, there wasn't 4G Internet. Te second, main speaker didn't work at all, so I could hear other people only using loud speaker. I sent it back. So, at first I paid for the transaction of my money from Australia to China, after that I paid for returning parcel and... 2 months I've tried to reach that bloody person Hellen. No one wanted to communicate with me. The result: I waste 3 month for all of this, lost roughly 100 dollars as post expences and had very bad mood during all these three months. The worst site. Do not buy anything there.
