I downloaded the software because I was searching for a text book, which ultimately I could not download. They first said that there was only a $5 charge but than charged more $70 without asking. So much for the bad side.
Anyway, the damage was done, so I gave it a try, just to see if the software was or not trash. Than, the surprise! The software is the best download software I've ever used: it allows me to download music, videos, books and more with an incredible speed (10min for a full movie).
To sum up: they have a very nasty and unclear pricing policy which I don't like. BUT, for this $75 they give you one of the best download programs I've ever seen. Up to you to see if it's worth it.
