My Dual Boot Hi12 is working fine. There is a handfull of Chinese apps but I could easily uninstall these so they are probably on top of the base ROM. Battery life is good and the optional keyboard I got works well in both Windows and Android. I think rooting is more difficult in later versions of Android but the tablet already has good app compatibillity in Play Store so unless there’s a specific app you need root for it’s probably not necessary.
