Kind of. Well, my brother does and I use it.
Honestly... you cannot go back once you have it.
A Wii game that is ~5GB (Whatever is the size) downloads in about an hour to two hours. Also, it downloads straight from the servers so you're not seeding it.
Back when we used torrents, we would always get e-mails from our internet provider to stop downloading stuff, but since we got that over a year ago, we haven't received one.
Another great thing about it is if it's like a virus or something, it gets taken down really fast.
