i was thinking about using it til end of summer. I'm riding trainer a good bit right now, b/c heat outside i can't get the workout i want outdoors. If nothing else looks like it would be a good motivator while on the trainer w/ all the workouts. You can also watch something else while data is at bottom of screen. I doubt the power is very accurate, but if it's somewhat consistent that would be helpful. If it sucks i'm only out $10.
