Though torrent is illegal, still used on vast range because its easy to use interface, nice concept and no other good alternatives to compete with torrents.
I am using torrents since 1 year and it is the best site for downloading HD, FHD, Blue-Ray movies. It is also good for downloading computer games.
Imagine you have hundreds ahd thousands of options for download a single movie and that too available in different size. Torrents makes our this imagination true . One of the best feature is that in u torrent ongoing task resumes even after 10 day and more.
The loading time is also good.
