I bought this product of jio 2 months ago and am still using it at present, and infact my at the moment internet provider is also is the jiofi. I got an offer regarding this online and bought it on 999 where its original product is 2000+. Well, I liked this product very much for everything it provided including its internet speed, connection reliability, as well as Service and support.
Firstly, Its internet speed is awesome with very high speed limit of around 200+kbps and also has got long range hotspot zone.
Secondly, Its connection is also awesome and it also provides WPS button for protection of wifi and much more
Thirdly, Its service support falls under "jio service support" which is always meant to work. Thus, overall I loved this product and would always recommend others to try out.
