Most download managers seem utterly pointless to me - there's usually spyware or other kinds of malware, and they often install browser toolbars you don't want.
Yes, what's your question? I find it's brilliant, especially in the evenings when connections slow right down and often drop in the middle of downloads. I'm in a remote location relying on 'copper', and regularly get download speeds of 500Mb/s, impossible without IDM. Well worth the money for me..
