Boox makes neat devices but keep in mind they don't respect the GPL if that matters to you, and their QC and warranty service is apparently not great either. Their subreddit is full of reports of dead displays which their support always insists is the users fault so they can refuse a replacement. They were also caught running sockpuppet accounts to cast blame on anyone posting about a broken display (not very subtly because that was the only activity on those accounts).
