I bought this device a month before, Still now I didn’t come across any problem. It comes up with a new display compared with the older version. It is compact in size which can be easily put in shirt and pant packets. It has a memory card slot which can also be used a pen drive. It’s power capability is good which lasts for 8 - 10 hours. The internet speed is around 2-4 mbps. The service is good, I contacted them for some help where sorted it out immediately. Worth a buy for users who have non 4G hand set in your mobile.
