Had it twice. They claim they don't throttle the speed at which you get movies. But I would order a DVD, watch it and send it back and wait for another. Used to be 2 days, then it would take 4 days, then eventually 1 movie a week. I complained to them about why they are being slower about it and they claim they don't have a policy to limit the speed at which movies get to you but obviously they do. If I watch a movie and send it back right away it took 3-7 days to get a new one. If I held on to the movie for a week and sent it back it took 1-2 days to get a new one.
I ended up cancelling.
