Jiofi is the most worst worst product of jio. It shows that through it many devices are conncted but in reality maximum 5 devices are connected. after connected more than 5 devices the speed is reduce.and it does not work. as Jiofi shows the speed of the net is aprox 20mbps. But in reality there is nothing. The average speed is in approx 1 to 2 Mbps. so my opinion is this is not good. And the battery backup of jiofi is vry bad. The backup of the jiofi is maximum 3 to 4 hour
