I'm very satisfied with the device. Did it then equally equipped with an anti-reflection film. Once set up, also with the help of an article that appeared at that time limited the Datensammelei Google and Co in c't. And since the thing is running without problems. Depending on the usage I have to the charger every 2-6 days time. SIM card from Aldi Süd with 500MB Flat. To make calls using my old cell phone. I have never recorded an update, not on the operating system (still 4.3), even on installed apps. Updates make it usually only gets worse or request added new rights. How it works best for me. Some Asus apps have automatically pulled an update and then shut down because the no longer ran at 4.3. This may be my only right. The front camera is unfortunately grottig, here I would like to see a good Selfie cam. Otherwise everything Top!
