I didn’t have ads either but being able to use KoReader is a good enough motivation for me.
- You can customize it a lot to your own liking and they do something clever with page changing that it seems a lot more responsive.
- Another thing is I used to have to convert epubs to KFX to get nice hyphenation and good typography but on KoReader you seem to be able to customize all those typography things with whatever epub you throw at it.
- Also, I have a local Calibre OPDS endpoint, you can add that in KoReader and download books over wirelessly. WiFi needs to be on when doing that but with a few tweaks you have read only root partiton so Kindle shouldn’t update.
Overall there are a lot of steps to it, if you’re comfortable with your current setup it’s not worth the hassle/time.
I got ads removed on mine by asking chat support. The only caveat is it needs to be registered to an account. If you get a patient employee and ask kindly that the ads are not appropriate for children, it usually works.
