## Questions & Answers

**Q: what's difference between new orange color and old black one?**
A: I had a orange one and after like a day of wearing it the edges got back. So I just emailed Fitbit and they sent a black one. If anyone would ask me what color to get I would say black or a dark color

**Q: Has anyone compared it to a chest strap heart rate monitor to check for accuracy? That is primarily what I want this for.**
A: Like many others, I had hoped to replace a Polar chest strap and wrist heart monitor (which I used for several years) with a single wristband heart monitor device.  Having monitored my heart rate (often daily) and (almost always) during exercise with my Polar, during many different activities and on many different exercise machines that display heart rate, I agree with those who have found that the Fitbit heart rate monitor is accurately only up to about 120 bpm.  It cannot accurately measure higher rates during intervals, especially quick changes in heart rate.  I know that during an interval when I go all out (whatever the exercise) my heart rate goes up to 150-160.  But my Fitbit Charge HR has never shown bpm higher than 130.  And often during intense exercise (even just on an elliptical machine or a stationary bike or a stairmaster), it just shows dashes and is not measuring my heart rate at all.  Extremely disappointing, and I will go back to using a chest strap when I want accurate heart rate info.

**Q: I'm a female with a wrist measuring 6.5 inches.  The small goes up to 6.7. Large starts at 6.3. Any suggestions on which would be better?**
A: If your wrist is 6.5 inches or larger you will definitely want to get the large. If your wrist is smaller than 6.5 you will definitely want the small. Accidentally grabbed a large but thought it would be no big deal since I was at 6.4 but no, definitely needed a small.

**Q: Has anyone compared the accuracy of the heart rate monitor to the Polar heart rate monitors?**
A: Even Polar heart rate monitors use an algorithm to **estimate** calorie expenditure.  And because the measurement is dependent on BOTH heart rate and oxygen uptake, it will be most accurate when measuring intensities between ~40% of your VO2 max and your lactate threshold.  If you don't input an accurate VO2 max into your Polar, then your "calories burned" could be off by a significant amount.  Same for all the new activity trackers.  When I was an Exercise Physiology student, our lab offered VO2 max and other tests to the community.
