Its a very good product. After using a month below facts I can summarize : -
1) It is very portable.
2) Battery packup is good, I got around 5 hours.
3) Network reception is better than mobile reception, I connected all devices at homes however max it can connect to 30 devices
4) Good design - squarish shape with smooth edges
5) Easy to configure.
8) No lags, delay or disconnection problem faced so far.
9) One can connect non 4G Phone to 4G supported phone through hotspot
Finally it is the best wifi I ever used
