µTorrent is the most popular torrent client in the world; millions of users enjoy it. The secret of its popularity is a light-weight size and surprisingly swift work. With a download package size of less than one megabyte, it covers all the torrent-tracker needs of a user and allows hassle-free downloading of any content.
In addition to the free version, a paid variant, µTorrent+, is available too. It includes additional functions such as an antivirus, the support for a large number of video and audio formats, a file format converter, and remote access to files. The price for the paid version is about $25.
