Obviously an amateur written program, bad interface, bugs (clearly there have been a LOT of bugs in previous versions, hence the high version number and regular "updates"). The good review below seems planted.
Very strange interface, badly thought out and labelled icons, clearly written by a small amateur programming house (very strange not-quite-English alert messages which make the application seem unreliable). And the really... hilarious... thing... is... they want you to PAY for it. That's just utterly comical.
Very fast downloads and pretty easy to use. If the download gets interrupted, you can just resume from where you stopped. Awesome app.
