With this device, you just have to be aware that it is incredible on a budget .. We can not expect the performance of a 600 euro expensive Ipads ... With the latest software, you can flash for free on the device it runs really smoothly. The system stability with Android 4.2 is initially very very good, but unfortunately deteriorated over time a little .. But sufficient. All games I've ever played with the tablet (NFS Most Wanted, Temple Run, Subway Surfers etc) ran without any problems and in the retina resolution of the display! For films this tablet is just perfect, since it also supports Flash, unlike the Ipad ... This so you can easily stream movies!
Conclusion: The one star rating from here is probably due to an old firmware! Price performance of this tablet is great!
