I bought this jiofi device 8 months back and I have been using it pretty much daily with jio offer. Its a great wireless device which gives good speed of avg 5-8 maps but problem starts if ur using it during monsoon season the signal becomes weak apart from that jiofi is a great compact device, it easily fits into your pocket and has got decent build quality. Price: Rs 2000.
The jio fi helped me lot.
