I have purchased Jiofi M2 on April 21 - 2017. It is a nice product. It is a small and very good looking product. I purchased it for Rs. 1999 . It is compatible for all the phones, tablet, laptop, PC etc. which has Wifi connectivity, it is not a factor whether it is a 2G device or it is a VOLTE supported device. in the box you get Jiofi, a 2300 mah battery, a charger and some guide for the product. I used to get almost 1-2 mbps internet speed in natural use. But the internet speed depends on the location, because I have seen in some particular places I used to get almost 3 - 3.5 mbps of download speed. When I start the device it is connected to the internet within 10 sec. I used to get almost 5-6 hours of battery life. The only con that I have noticed with some extended usage and while charging the device heats up. so I think it is a good product for this price point.
