I bought this Tablet (Cube Iwork 10) fews months ago and I haven’t anything to acclaim. The only change that I made was change the charger and cable, now I use a charger with 2A from a cellphone BLU and I formated it to Windows 10 only! I let charging all night (usually 23PM-7AM) and complete 100% without problem! No problem about “black screen” or other issue! I have the magnetic keyboard with mouse and working like a charm!
