Does what it says on the tin
Does what it says on the tin. Not only, but when converting a kindle book, it warned me the version of Kindle I was using wouldn't work with it. So, from a single button within the Epubor appl., with the appropriate warning, it uninstalled the version I had, downloaded the version it needed, and installed that. That is a level of attention to detail, you do not normally see in S'Ware development.
