My Inspire 3 was a gift to myself because I have atrial fibrillation. I am usually good and have only had 3 major bouts, the last one while wearing my fit bit. Imagine my shock when my Fitbit was showing a heart rate of 107 and my blood pressure machine showed 154! Not only that, but when the paramedics and hospital were registering a high of 188 and up, the highest Fitbit went was 132. I also was.praised by Fitbit for remaining in the zone for over 7 hours. What a joke. I had been considering upgrading to the premium feature, but discarded that. It's just a watch and alarm clock now, it's only accurate use.
