I had bought this device in 2012 and I am still using this as my secondary device.
It is so laggy that it takes about a minute to open any app even if I have reset it a thousand times.
The looking of the device is decent and it has only single sim support.
It offers a 1080p screen which is decent but heavy games and heavy rendered movies do not run smoothly on it.
It is not at all touch responsive as I mentioned above.
You have to play games at low graphics which is very frustrating.
So I suggest not to buy this tablet.
