I am still rocking my original band 1. I will eventually need to replace it with a new device since MS decided to cancel the band. One feature I love about the Band 1 is that I can create workouts on the Microsoft Health Website. I do a lot of Crossfit workouts and this Band is great for that. For example: I will do a 20 minute circuit where I will run 400 meters, do 10 reps of deadlifts and 10 pull ups. I just press the button to go to the next exercise. The band buzzes automatically when I complete 400 meter run so this feature works great. Does anyone know a fitness tracker or watch that has those features? Greatly appreciated.
