The tablet is with me on the desk, no meters from the cable D-Fi router. Here the machine receives just as WLAN. But I'm out of the office (max 5 meters) has already no longer receive. Other devices in the house, have even in the basement behind thick concrete walls, with the same router, still the best reception. Add to this that the device keypad is slow, and often does not respond. Using your fingers to write could hardly, with the pen just like that. Some keys respond only when they are tapped at the corners. The pressure point on the appeal to the keys, and the whole tray is so different, preventing normal operation is hardly possible. Have the tablet actually bought for my grandson - but can I forget who comes not so klar.Sicher has the tablet some equipment items that are usually found in more expensive models, but what good is it if you do not work properly with it in everyday use can. That it is generally very slow, the negative image rounds still from. Too bad. For me, a smooth bad investment.
