I too have brought the products with the greatest scope. I find the pen itself OK but as my predecessor already wrote: Something unprezise. Calibration has indeed brought a little more accuracy, but that's about it unfortunately.
Much worse is the wireless adapter. Now I have already tried in different routers and company suppliers (D-Link / FritzBox / Speedport) the pad and get to the result that the signal is extremely weak! Even next to the access point, the connection is very bad. And since there is currently no update / new firmware. Unfortunately.
Another negative point is the USB port. This is very difficult to recognize - or not at all a USB stick. Again, I have tested various sticks. But an external hard drive or a USB drive. USB LTE STICK ... None - no emotion. It seems the USB port are not re-power on its own - so Unnutz!
It becomes interesting when you connect a mouse Bleutooths - probably noticed the pad has several search attempts needed - he found the mouse, installed it and I could use it wonderful! - But again, only as long as I was not connected to the WLAN. By connecting on WiFi and runs the Bluetooths mouse, there are in the mouse so extremely-long delays for a pad ... Incredibly this price !!!
I figured. OK - perhaps the pad should then be joined current. Unfortunately none.
With a UMTS card but the pad is wonderful deal!
For the Windows 8 Pro running extremely well! The pad is very fast and can be operated wonderfully. The resolution is amazing and the sound very good! The processing of the pads I find great and the battery - brilliantly. I've had it for almost a Artbeitswoche only are - little genutz / it was on all the time and the battery was still nearly full! But even in everyday use - I had to load only every 2 days.
I've got my pad just sent back. I hope that it as a reasonable replacement pad of manufacturers coming. Because I can not imagine that the bugs will be simply by a few updates away.
In any case, the same Sympthome like me on the Offz. Home / Forum read!
I say yes - to a class PAD when a few bugs are fixed!
Many thanks
