I bought the device and when it arrived really pleased. It also has really good fun. Nevertheless, I had a short time notice that despite the stated performance, the speed has waned. Added to this was that there was a Wackelkonkakt in / on the tablet to charge the battery. But what I find from worst is the fact that the tablet can not be charged via USB. I already have a smaller tablet, because I'm on the train on the road a lot. However, this is in the long run, become too slow in increasing body of Apps. I've (13000 A) brought this tablet a USB Power Pack and have assumed that all tablets have a USB charging function. Unfortunately, this was apparently a misperception. Now I must unfortunately return dasTablet.
