Conclusion after 2 years: I use the tablet now just under 2 years. Except for the display, which had to be recalibrated several times, no problem. A few weeks ago went the battery performance noticeably. Finally, the battery then only held about 1 hour Then came the thick end. The battery has bloated and housing pushed apart: total loss. Since the two weeks before the expiry of the warranty has happened, I have the equipment to service with request for Garantierep. sent. The first phone call was not told that the battery only for a period of 6 months there and they wanted to give me an estimate. After 2 weeks, then came back the package: Completely new unit, replaced at no charge. Of these, some other manufacturers could learn ne disc!
