Stay away Mac users. Be wary, Windows ones.
I was excited to try this out given the high reviews but on their website, half of the 5-starts were actually the company "replying" to their customers as they rated themselves. As for the program itself, it did not work at all despite the several tutorials I have tried. Mac users beware, it is a will suck you into hours of futility. For the most part, I feel like I wasted decent money on this and still haven't heard from customer service for a refund. You're just bombarded with more tutorials. That's another thing, their tickets don't work and you aren't issued any official number -- you just get contacted with a Gmail account which doesn't seem very reliable. I will change this rating when I finally get my money back because I will still like to try the Windows version. That "trial" version went better even if you are not able to convert a full book.
