A:Answer If you need to see a constant heart rate, I recommend the Microsoft Band 2. I have had mine for 3 months now. Wow! It also tracks my sleep patterns as well as heart rate, steps taken, work out progress, Golf course actions...etc... I could go on with many, many more things this Band does... Better than just a "Health Band"! If you are serious about your health and want a great Data aggregator, this is the only one I would buy!
