Mostly great
Ponied up for paid version. Well worth it. Easy to set up. Love that you can customize intervals or choose from presets. Like that I can choose what music to be played. My only gripe is that I can only choose songs that I have on my iTunes playlist rather than other Platforms.
All in all it does what I expected..
