A little drawback is that the tablet sometimes by itself turns on when it is in a shell.
It is not yet clear how the battery can be replaced.
But my Probelm is the display resolution: 1280 x 800 pixels are really good standard. But the small letters are slightly blurred and my eyes begin to ache. This continues for a few days, no matter what you did with the Tablet. With all other devices I've never had such problems. I can spend hours surfing with my Samsung smartphone 800x480.
I had the direct comparison with the Nexus 7 model 2013 with 1920 × 1200 resolution. A difference like night and day! The photos at Nexus are much more detailed and you can read faster. Scripture from Mark 8.0 wishy-washy appear, however.
Before now some readers indignant: Except for the resolution the Mark 8.0 is really a good tablet. Everyone reacts differently halt it.
