I got one a few weeks ago, put a post here about the screen not being sensitive enough. After much fiddling around, I noticwd that there was a factory screen saver installed. I took that off, works a lot better now.
Windows 10 works great on this one, as does Android. I tend to remain mostly on Android thought, as I like the apps better.
Cube use stock Android, which is a lot better than Teclast and Onda, which add their own chinese version.
