[quote name='Genocidal']It's a fake idling program that from what I've heard from some users, doesn't really help much, if at all.[/QUOTE]
Wouldn't say it's completely worthless. It allows you to be online than any normal person could play TF2, and doesn't comes with the actual computational power needed to just idle in game. It's just a time thing...the longer you're online, the more rolls you'll probably get. With more rolls, it is expected that you have a higher chance of having found a hat.
