This tablet really exceeds all my expectations. An OTG cable is included. So you can play Software with an external drive or use a USB stick. Games function properly. GPS is also available. Printer installation worked smoothly. Windows 8.1 was also very important to me. That was the Vorauszetzung to buy a tablet with Windows for me. The Tablet holds well on the keyboard and is easy to remove it again. In tablet and the keyboard has a battery pack included. The fact that only 1 GB of memory is available, in my opinion has no effect after. The tablet starts up fast and turns again quickly. Windows and programs are started smoothly and ended again. Videos and music can be played, but no DVD via an external drive, because it is no software available ISTT. It was very on functionality and that's when the tablet actually succeeded. I am delighted to have bought this tablet.
