Electronic waste in plastic coat

First One thing ... did not buy the device itself but luckily my girlfriend got inherited it. Still, I had to test the "pleasure" the device.
First there were problems at power, battery repeatedly charged nothing went. Today tried again before I call the support and see that it was ... unfortunately ...

So here are my experiences

Display:
--Easy only scrap blurred due to the low resolution

Service:
must --man far too much power to spend in the operation
--Ruckeln Part of everyday life
--After Pressing buttons does not always happen that

WIFI:
--After I had turned on the Wi-Fi, the device crashed

Speed:
--langsam, watch due to the low CPU clock speed, photos no fun
--Gerät React very delayed to pressing of buttons

I can not understand how other users can rate this unit as high, seemingly made no comparisons to iPad and Galaxy Tab. Of course for the price range you can expect anything, so I would have this equipment not purchased ... rather invest more money and then also have a device that is suitable for everyday use.
Because at least I know that my Androidsmartphones it's not the operating system)
