The reliance jiofi is a affordable product with some good and handy features.
NOTE: I got it three months ago and with jio cheap data plans it is very satisfying and also I got it in just 999 in exchange of my old mts dongle which was a lot worse.
PROS: It is wirelesss so once charged you are ready to rock for almost 6-7 hours most probably.
Handy hotspot, a light weight device, easy to carry and easy to use.
You can connect 30 devices at the same time which is already too much.
Internet speed depends on your jio connectivity in that area.
One button on off system, quite easy for all,
Wps feature also inbuilt available for fast connection.
CONS: Gets a little warmer when you use it a little longer which is not comfortable if you are keeping it in pocket or in hand.
Battery capacity is just 2300 mah which feels weak sometimes.
Plastic body so if you ever drop it you are going to loose it.
