I have a boox page and i love it. I don’t use it for reading manga but i haven’t tried it so can’t speak on whether it would be good or bad. It’s amazing for books though, great battery life and SD slot which were huge for me. It also runs regular android so I use Koreader to read books and you could definitely download Mihon to read mangas.
What’s the advantage of using the wireless adapter over bluetooth for the controller?
