"Terrible heart rate it has never worked."1.0 starson by missblip
Pros: gps is fun to have and I enjoy seeing the map displayed and logging each of my workouts. The switch from arm to bike quick release is pretty awesome. The wireless update to computer makes this a breeze to download updates and track all workouts.
Cons: systems don't actually work. how can you trust it for $500 it should work perfectly. The heart rate is the part I train with the most and it is completely unusable. Guess I'll buy a watch for each arm one timex/polar and then the Garmin.
Summary: I would not recommend
