We've been members for a little over a year now (3 DVD's at a time). They will throttle you if you try to watch "too many" DVD's in a month. They will claim that your DVD is not available from the closest distribution center, and then send it from all the way across the country, resulting in another 2-3 days for shipping. As long as you only want to watch 1-2 DVD's per week things ship quickly.
Many of the older DVD's are scratched and some have been cracked. Watching the badly scratched ones will depend on how good your DVD player is. Getting the new releases has been hit & miss. Sometimes we get them right away, other times it takes weeks.
It hasn't been a terrible experience, but I think we're going to cancel later this year.
