Can confirm. I own a Poke 5P and the ghosting is really more obvious until you've fiddled with the settings enough - and I do mean fiddle here. Might take a while.

Other than that I'm a real fan: latest update delivered dark mode (black background, white text) and like I said above: no ads, no Amazon-DRM, all formats, cloud storage (if you want to), TTS, annotations that are really comfortable to handle, bluetooth.

Boox suck. Stay away. Horrible android os, low speed, battery and hardware quality issues, and dodgy Chinese practices all around.

screen is not as crisp and a lot of ghosting
