I m not satisfied totally with thi gadget because its speed is not so fast as they told that download speed is 150mbps and upload speed 50mbps but because it is fre upt 31st March 2017 that’s why it is good. However its speed range 2 to 3 mbps.
Router’s wifi range is 20 meter approx its battery life is 5 to 6 hrs after full charge. it is portable device so if you going somewhere you can easily carry this and enjoy anywhere. Upto 10 device can connect with this but if you connect more than 5 or 6 devices affect its speed. Jiofi m2 has a display it shows battery life, network strength and wifi .
