So either I have a Monday device caught or all the good reviews are where the thing is far from sellers in stock and they are to be rid of it now. I share the opinions expressed in any way. The stylus brings entirely of often. When I write with the Tata stubbornness, holding denstift mostly in the hand, or when I leave my Writes table, then I put it in the bowl made it on the tablet. In ungefährt 90% of cases in resumption of pen operation (ie pin is to be used), it does not work the first time. I have to knock the tip 2-7 times on the tablet, so that the pin back in contact with the tablet and visible as Mousecurser on the screen / appear. I have the battery already changed twice so because it is not. The tip of the pen I have changed. The unit seems to have a problem with the cable and USB. If all else fails with the pen, I have to unplug the cable and plug it in again several times, so that the "whole" is working again. All in all, a total "nugget".
