We had two, and both batteries are dead. No longer charging at all.
Additionally, even before the batteries went, video playback was far from great at the end.
I used NewPipe for youtube videos and VLC for downloads. And while once playing, it worked fine enough, the UI interactions were frustrating because of lacking responsiveness, and the 7 inch thick bezelled form factor made it hard to watch anything without holding the device in front of you.
We've since switched to a couple of cheap 10" tablets and they provide a much nicer experience.
