I tried the free trial version
I tried the free trial version. It was possible to remove DRM only in 20% of the text in one Kindle book (as same as it was announced on the site). A paid license is required to process the rest of the books. In the processed part of the book, instead of the requested PDF format, the Program gave me a TXT format. No spacing between paragraphs, no indentation in a new paragraph - nothing. Reading this format is terribly inconvenient. It is unclear how tabular and graphic data will be converted. If the trial version showed not only the TXT format, but how the paid version actually works, it would be easier to make a decision to purchase a license. Now I don’t even know if I will receive PDF for the rest of the books or the program will also issue only TXT.
