Recently I purchased JioFi M2 router for INR 2000. I recharged with sim also.
PROS:
We can connect upto 31 devices.
Indicators for battery status, signal strength, connection status, wps status.
dedicated wps button.
we can control the device through web jiofi.local.html
wireless sharing through SD card
CONS:
Taking 7hrs to full charge
Wifi range is very less. maximum 10 meters for full signal range.
Device gets heat.
I used this for two months happily with out any problems. But after 2 months the device started head abnormal. The signal strength also came down. I took it to service center. The service center people receiving worst. The asked the bill xerox. the actual bill I have is oil papered bill like super markets bill. The letters are evaporated and total bill display is dull. But it is able to find the purchase date. Actual problem is when I tried to make it xerox nothing is coming. I scanned it and make a color print to satisfy the service center people. After that they did some software update within 5 minutes and gave it back to me. But the problem was not solved. I took it again to service center. Again they took color xerox and did software update. Now it worked for one week. Again same problem. each time I am making color print and they are doing software update. But they are not replacing or repairing the hardware. I waxed this process and thrown it away.
