I have very bad experience about Micromax Tab Funbook. Reason short durable, service center will take 1 month or more to repair and wrong commitment repaired date.
They will send you sms about your device ready and while collecting the device they will make some unbelievable reason. Like, courier got stuck, sms confirmation got stuck due to technical issues.
After all I would like to share my thought instead of purchasing Micromax got to Samsung(my preference) or others.
