This program is amazing. It takes up very little processor time, 40-50MB of RAM when very busy, is very stable, and loves to do what it does.
Very easy to use, simple, intuitive interface. I can stare at the 3D Swarm for hours. It's an interesting thing to watch. Comprehensive and simple (but complete) preferences, including max upload rate, max uploade rate settings for new torrents, max up and down connections, easy file lists, and so on.
This has, with one use, become the only torrent client I'll ever need. Beautiful, stable, simple, light.. this one's a winner. You owe yourself to give it a try if you ever, even ONCE, want to use Bit Torrent.
You definitely can't beat the price.
