The first device did not turn on ("Dead on Arrival"). On the second unit, the touchpad was after 4 weeks from complete.
Compliments to Medion / Amazon: exchange and refund went smoothly !!!
Then have a device at Aldi for 50 euros less and double RAM acquired (4 instead of 2 GB). With performance and operation, I am satisfied. The Touch Pad is acceptable, the keyboard is good.
The complete Microsoft Office environment runs quite fast.
The battery life is for "in-house operation 'ok, albeit as a tablet unconvincing (real about 3-4 hours).
The weight is quite high (860g tablet, 840g the docking station), if you hold is impossible.
Unfavorable is the "smearing" of the display, as also described other users. After 2-3 days, oily streaks occur on the screen (always in the same place), which can be removed with detergent and a soft cloth.
Total: Moderate quality at an affordable price
