got my tablet also on banggood i have to say excellent retailer they handle all the bios updates before i touching the device so no need to do the dirty work
My only concern and this might be windows 10 problem, i don’t like to browser with Edge (no plugins) and all the other browsers (Mozilla, Opera, Chrome, Vivaldi) they all seem sluggish no smooth scrolling, i guess hardware acceleration its not activated somehow but Edge works all fine, i upgraded the display adapter threw device manager but still the same(driver date 18-Nov-15, driver version: 20.19.15.4331). I can’t run a live ubuntu or manjaro usb so need to search more what kernel supports this chipset z8300 if there is any.
