Garmin vívofit Fitness Band: Start each day with a personalized and attainable goal. Designed to be worn 24/7, this water-resistant fitness band has a battery life of over one year and reminds you to move throughout the day. The included heart rate monitor helps you accurately track calories burned during everyday activities and your more intense workouts.
I'm very happy with the garmin vivofit. It tracks my steps, and has me increasing the number of steps daily. Also let's me know when I have been inactive for too long of a period. Doesn't require recharging, so all my steps count. One thing I don't like is that it doesn't count the time pushing a grocery cart, or riding a bicycle.
