I recently purchased an Xteink 4 Pro. My understanding is the built-in software is somewhat ok. You can find reviews on YouTube if you want to know more.
For installing CrossPoint, that is very easy. The CrossPoint website walks you through the installation, which only takes 5-10 minutes. After that, you can put content on the device using the build-in SD card, via Wifi, and a few other methods.
