I agree with others it's very expensive for what it does. It doesn't take much programming to cost over $100. For example, a log of when the backup pump runs and how long it runs at maximum heart rate. Also, they could add a feature to see how charged the battery is and maybe track the date it was installed. I can think of many others.
