A decent 4g hotspot router from reliance jio. Better from its previous models.
It provides good connectivity and can connect upto 32 devices 31 via hotspot and 1 via usb.
Really a tough device and can not be damaged easily on some minor or major falls.
It consists a 2600 mAh battery which can last upto 7-8 hours.
One thing which impresses me is the range of the device which is more than enough for a 3 BHK house.
Connectivity is very good and you can also use it as a wifi drive for transmitting data over hotspot as it support a micro sd card.
One drawback is that you can not insert some other carrier sim in it because it is locked. currently reliance is not offering any special plans for jio fi.
