I think that micromax p680 tab is very good product launched by micromax in2015
This tab comes with a wide screen of 8inches.
Camery quality is good front comes with 5mp with flash and front one with2mp good for video calling
Ram is of 1gb
Internal memory is of 16gb quite good
Sound quality is very nice.
We can connect external storage also like pendrive
Calling features suports 2 simS slot with 3g network support
No heating problem than other tabs
And doesnt hang
Battery backup is also nice
So I recomend u all for buying this tab.
