How accurate is the heart rate null

I just wrote my review of the product and only gave it 2 stars because I've found (for me at least) it to be hit/miss on how accurate it is. Some times not matter how high, low, loose, tight I have it, the heart rate feature is WAY off! It happens just enough to make me question how accurate it is every other time of the day. In one of MANY examples I have, I was doing HIIT cardio, was completely out of breathe, sweating, heart is racing and the Fitbit says my HR was at 72bpm...in reality it was probably in the 155-175 range.

Very accurate. I actually had this on while I was at the doctor and it was only 1bpm off.

I have found it to be close within 2 to 5 beats per minute. It averages out with time and it is really just a reference from day to day and activity no no activity. It pretty accurate.

Most exercises, very. Occasionally if your wrist gets too sweaty or your hands are stationary and below your heart it can lose the heart rate

Very accurate in my opinion. Sometimes I test it out when I'm on the treadmill and it always has the same HR.

When I'm running on a treadmill it will usually read out about the same as the hr sensors on the treadmill so I would guess it's pretty close.

Pretty accurate we compared it with a professional one and deviation is nihil

Very accurate if you have it placed properly on your arm.

As far as I know it is very accurate.

Not Accurate At All...... and the sad part is that Fit Bit know this....
