Hopefully some others with the BOOX Max 3 or Lumi can comment here, but in general, I think BOOX has done a fairly good job with preventing ghosting and other artifacts with their line of e-ink tablets, and while the vertical scrolling is not particularly smooth (the screen updates/refreshes every second or so), it works just fine if you aren't trying to utilize automatic scrolling with a constant slow scroll. I would recommend instead using scroll options like scrolling 30-50% of the page at a time and making the scroll speed instant.  With the next update, I'm adding an option to scroll half of a page at a time with the vertical scrolling mode, so this allows users without a pedal to operate this way.
