I am a huge Garmin Fan. I've had the Forerunner 305, 310xt, 910xt and, now, Fenix 3. Overall, I am very pleased with the Fenix 3 but give it 3 stars. I am a triathlete and use Swim, bike, run functions primarily. I won't go into details of the functions as others have done nice descriptions. The best and most comprehensive is the DC rainmaker..
