I've been using Torrentzilla for about five months, and after a short time of having a terrible ratio (due to my limited bandwidth), I've been able to get into the best parts of the site. They have great content, and I have never downloaded anything with malicious content. TV shows are often on the site within half an hour of the broadcast ending, and movies are are very good quality. Even though there aren't many people on the site, download speeds are very high, and I have been very satisfied with my time there. Don't even hesitate to join up, you won't be disappointed.
