I had bought zapak game box extreme in Nov last year at 3.5K for my children considering it as a cheaper option compared to PS4. But it is worth mentioning that u should not buy very cheap things for atleast children related to electronics.
The item was totally waste considering the visual graphics which is very bad, the worst battery life which heats up within 10-15 mins after u start playing games.for the camera, u consider that it is not there. the picture is not clear. One few of the downloaded games were upto the mark which children enjoyed but it could also not last much long. Go for Nintendo or PS4 where u will get good quality and u can download ur own games with better storage capacity.
