Amazed...
...that you did not include a GPS running device such as a Garmin or similar but did manage to include a foot massager and a puzzle. My Garmin has a heart rate monitor and a cadence sensor so is really useful for both running and cycling, a free website to upload all of my exercise as well as a standard export format which many other running and fitness websites accept.
The GPS is also accurate and there are a variety of options such as virtual training partner, courses (with route map), auto-lapping, auto-multisport, pace and heart rate zones and the 400 series have heartrate-based calorie calculation.
I have used one for a year now and wouldn't be without it for a long run or race.
