I am using it from very long now I do watch lot of online videos and it never buffered on even highest quality possible . Its downloading speed is very high and I had downloaded lots of movie within no time .even whenever I upload videos it never take long time and the price they are taking is very cheap .that is the reason I am using it till now and once I had little problem so I called their customer service and they solved it within minutes , I never faced any problem with it. I really trust jiofi alot even when it connect to lots of device it's speed never reduce .
