Up on the windy cover for card slots, I was very satisfied with the device. The display is OK responding touchscreen good. The resolution is not the highest, I had no problems with it. The battery seems to be sufficient. A movie was 2 hours after the battery was at 79%. The purpose of the keyboard has not been revealed to me. It is a keyboard for Windows, on the device running Android. After all, it works well and who has to write long emails or texts, they might want to use. The device should be used as a navigation system, in addition, it was too big. I sent it back and now get a 7 "device of Xido. The included user manual is not very revealing, but it is soon a detailed available. Enquiries from Electronicfox be answered quickly.
