I used this portable and found it great with working data cable and good enough space as offered. The device never hanged or slowed down,
One thing can be little fishy that the device gave little slow speed i.e. 14mb/s & reading 20mb/s but ot is accurate enough.No heating problem, for whatever long hours you use it adapted,
A really cool cover I got with it when bought from snapdeal offers,
May be felt little heavy, like a powerbank) -
Overall fantastic running no much issues,
