Calibre is great for me when syncing epub/mobi books from my computer to my Kindle Paperwhite (I don’t think I’ve ever encountered a major problem in this particular process, only on very old books which it has trouble converting). Besides that I use it to convert epub/mobi books onto html which is where I like to read when in my computer (using the browser, chromiun or firefox, which means I don’t use the screen reader of Calibre, this way I can make easy modifications with css and inject css to highlight the most important parts with several different encodings allowed by the extension I talked about in my answer).
It’s too feature-rich and heavy and it gets in your way, but it solves many simple problem if you use only some of its features.
This is the open-source repository and I recommend always being up-to-date with the latest release (that may solve some of your problems). Besides that I really recommend Calibre, it’s an essential tool for my purposes.
