First of all i have to thank Danny, this is the best thing since Fernando Torres for me! He spoke about this a few months ago and was showing off the kind of download speeds he was getting but unfortunately it was only for Linux so i could just watch in envy.Now its available in Windows! I say..delete all download managers you have and install this one!! I have not seen download speeds like this one EVER!!
Have a look at a Print screen of what i got yesterday ->
Look at that Down Speed!! My pc has never experienced 98.3KiB/s and the highest i achieved yesterday was 105.4KiB/s.It normally takes me about 6-7hours to download a series which i can do in just over a hour! EVERYONE SHOULD HAVE THIS ONE!! Have a read of the below courtesy of Danny 
What is Deluge?
BitTorrent Client for Linux, Mac, and now Windows. Works on almost all desktop environments. KDE, GNOME, XFCE, Windows and others. Deluge is lightweight with low system resource requirements and this makes it standout better when compared with others.
Deluge boasts an extensive list of features applied through the use of plugins. My favorite would be the full stream encryption feature which disables my ISP’s throttling capabilities on BitTorrent traffic.
- Web UI
- BitTorrent Protocol Encryption
- Mainline DHT
- FAST protocol extension
- µTorrent Peer Exchange
- UPnP and NAT-PMP
- Proxy support
- Web seed
- Private Torrents
- Global and per-torrent speed limits
- Configurable bandwidth scheduler
- Password protection
- RSS
- And much more!
