The middle section of the video is rather funny because whoever is throwing the ball has my athletic skills. They keep missing the device.
BTW, the first section of the video shows 2 screens, and only one is the newer HD E-ink screen. The black frame is the older screen, and the reason it broke is that it has a glass backplane. The newer HD E-ink screen uses a metal foil backplane (developed by LG Display I believe). As you can see from the video, it's a lot sturdier than glass.
