very good device, fluid with Google certification. you really feel double heart and does not even notice that there are only 512 MB of RAM. I have not been tested all the videos but virtually any bed with an additional player. I did not put the maximum score because it is quite difficult to charge the tablet when fully discharged. then the update of android 4.1 (lelly bean) is not yet available on this unit but will soon be available. if you want to use it for basic use (+ içnternet videos ..) you can dark. by cons I have not tested the device with large applications.
