Let me start by saying that this is NOT a simple, typical Mac application. It is a server that runs in the background - to use it you must point your web browser at it. The documentation is somewhat sketchy, so if you don't know what I just said then maybe this app isn't for you :)

Once you have it set up, it is like a rock. It never crashes, it always downloads the whole nzb, and it is as fast as my internet connection - able to open as many connections as you ask it to. It even can be set up to primarily download from your (free) ISP news server and then use the paid server for fills.

My favorite feature is the "black hole" folder. You can designate a folder - any folder - as the nzb "black hole". Any nzb dropped into this folder will be automatically downloaded. It's fantastic - you can just drop in a bunch of nzbs and then check the download folder a few hours later.

I'd give it 5 stars, but it is so un-Mac-like that I had to knock one off.
