I would say this device is really a piece of innovation, small, ability to sustain 5 hrs with a 2300 Mah battery, give near around 28 to 50 Mbps speed which is the indicator of good internet, in some cases internet speed reduces to 5 or even 1 mbps which is also okay assuming the network traffic or so. But there registration service is like delhi traffic jam at every point there is problem, registration process is not that hazzle free and there service can do better what it is doing now, I would recommend this device as it is piece of innovation and provides good internet
