Anyone have experience with Daily Burn (the streaming work-out service)?

My preferred way to exercise is gym classes, but they seem impossible to fit in to my current life. And I am having trouble getting to the gym at all, since it involves me taking time out of my (currently very shortened but not with less work) work day.

Daily Burn looks like it has a great variety of classes, and I feel like the new work-outs each day would help me stick with a routine. But I also hate signing up for something I don't use
