I'm not a computer expert, but the image quality is very good for the price in my opinion, there was no Rukler when playing HD videos from the external memory card. The sound is good through headphones, through the built-in speakers as standard. After 3 hours of video battery to 2/3 was empty.
Per-Fi to get quickly to the Internet, the pages are built quickly.
As I said to a layman like me makes the Tablet everything I expected of him.
Have the Tablet purchased new locally for 49 euros, therefore so 5 star in the price performance ratio.
