I’ve got mine last Friday, bought on AliExpress on the 15th Sep. -20% sell off.
I do like it, win 10 home 64bit updated to my language german and all other updates fine.
Android was 5.1 and no newer version, however you can de-install (allmost ?) all chinese apk. and go with google apk.
Aida64 shows me rooted but SU won’t install proper so no real root. Hope we’ll get a hack for that.
