If you are going to buy Chinese Tablets which are sold under "Infotmic" trademark, be careful about the seller. We had a very bad experience with a company called YUQI in Shenzhen and its manager called Peter.They showed very aggressive before selling the items but after selling everything changed. First we encountered about %25 failing items just coming out from the box specially in battery DE charge and more and more failing items in display and battery after 1 month of work. When we asked to use the warranty they just decided not to answer our emails and when we sent too many emails to them, they just answered and asked us to send the items to them by Post service. The agreed to pay half of the costs but when time came to pay, they just told us they are not going to pay for the customs and we should pay for everything.I have never seen a company like that and their manager has a very bad attitude.Be careful, either don't buy Chinese tablet or forget about YUQI, the worst company I have ever worked with!!!
