Small Review after 7days of usage :
1. Device getting warmer if we continuously use it for more than 2-3 hours. It's a common issue with all dongle and Router I think .
2. It's having battery capacity of just 1500mAh , and it giving 5.5hr on average . It's taking almost 3.5-4hr to full charge with supplied usb B type cable .
3. Range is not that great.
4. It can connect up to 10 devices at one time , though I've connected it 4 devices (2 mobile, fire tv stick and echo dot ) .
5. It's a single band router only having 2.4Ghz band, u can't expect more in this price segment
6. It has only 2g, only 3G, only 4G mode .It's a plus point
Here is the speed test result I m getting
