I am been using Jiofi device since 3months and I am going to share my experience.I liked the design and style of Jiofi and come to its speed and coverage and specs.So it can connect upto 30 devices and the network signals and speed is very good.It cost me 2000rs per device and I am really and happy and satisfied with the product.I recommend to try the Jiofi device those who use wifi.
