I've been using it for years... still haven't started watching the streaming stuff, mostly 'cuz I like getting the disc in the mail and going "oh yeah, I forgot about this one... cool!"

I don't do torrents, etc., so I can only compare Netflix to what I used to do (stand in line in a smelly B-buster store (why do they all smell bad? Is it just me?), get two or three discs, out of which at least one (usually the just-released smash hit) had clearly been used as a coaster and would not play- always!!! then have to run down there to drop the things in their box before the return date, or get charged extra.
It's way better than that, I can assure you.

So far, in several years, I've only received two discs (out of hundreds) that were too scratched to play, and they always arrive when they say they will. At least two have been lost in the mail, and they didn't seem to care (no fee for replacement). And I can hold onto them almost indefinitely... just can't have more than three at a time.
