It works really well, as long as you don't have a battery saver app like Juice Defender installed. They seem to compete with each other.
It basically works the same as JD's location service by comparing GPS data with tower data to determine if you should be on Wifi or 4G. It does scan these two radios, just not as frequently as if you left them both on all the time.
