It is! I got a Boox Note Air 3 C (then removed the matte screen protector). It’s fantastic for reading comics, and NewsBlur works really well on it!
The only eInk feature that would be nice is if NewsBlur was able to assume pages and cube able to click the tablet sides to go back/forward for an article — but truth be told this Boox Super Refresh tech makes scrolling on an eInk device painless. Heck, it even shows videos at 3fps! So far I’m thrilled!
Thank you so much for fixing my account!
Edit: I added some pictures of NewsBlur on the Boox Note Air 3C.
