my roommate used them for a month or 2. good selection for sure, but the turn around time took too long since you had to wait for them to get your mail before they would send out the new one. doesnt help that their only mail place was based outta cali.
My son's used it for a year now. Yes, it's much slower than netflix since there's no local ship center, it takes about a week from the time you send out a game until you receive the next one. But it's a good service, and they give you monthly credits towards purchasing used games.
