I bought this tablet for Rs 40, 000 as I was looking for a tablet.Lookwise the tablet looks great, but performance wise the tablet is not good.It has a single sim slot with 3G compatibility but NO 4G is present.Baterry is unable to handle whole day activity.Only plus point is its S PEN by which you can virtually do anything from taking notes to modifying photos etc.Screen size is 8 inches and is a boon for studying notes and other office work.Resolution is not great under bright sunlight.OS is upgradable to kitkat 4.4.Tablet lags on doing heavy work and using mutiwindows.RAM is 1 GB and internal storage is 16 GB which can be expanded by 64 GB( personally tested) .Rear camera is 5 MP and takes average photos but front camera is very poor ( only 1.3 MP) .OTG cable is not supported.It id also possible to call from this tablet.Finally , this tablet is good for taking notes and recognize handwritten notes by S PEN , but for other functions this is an average tablet
