Ive got a libre pro and my biggest dislike so far is less than stellar battery life 12 hours tops, I have to charge at least one a week. I love the easy to read screen and the libre pro's ability to handle drm'd epub book formats because I do like to ready some popular sci fic, mystery, spy series books that I can buy online or download from public library's , so no I don't hate my libre pro but I do find it battery life disappointing. P.S. honestly my favorite format so far is plan text it seems fill the screen the best and give the best battery life, Why ? Have no clue
