First of all, bear in mind that this app was originally written for another operating system, which means that the Windows version, according to the author's own words, is not as stable as the original one. In fact I got the odd error message while testing it, but other than that, the program worked fine. Transfer speed was excellent, along with the array of tools the program puts at your disposal to handle torrent files. Also, the program was totally unobtrusive for the user and very light on resources.
Deluge features a clear, uncluttered interface where you can easily manage all your file transfers and see information about each one of them. Also, the program's configuration settings enable you to tweak its behavior in great detail: you'll be able to limit bandwidth usage, configure a proxy server and also enable special plug-ins to add extra functionality to the program.
In all, Deluge is a powerful, easy-to-use BitTorrent client that's worth a try and will hopefully improve its stability under Windows in future releases.
