Isn't this how all of them measure your heart rate? , save for the ones that use the strap.

I've got a basis peak and I find it to be accurate enough to within a BPM or two.
Even Basis , fitbit's competitor, doesn't make crazy claims that it is wildly inaccurate, according to their own study fitbit has a margin of error of 8.7%. If anything its in their best interest to skew that number up as much as possible.

Sounds like this is a case of someone not wearing the device properly.
It can't be loose on your wrist and you need to move it down (towards your elbow) if you are doing some intensive activities to get a better reading.

3 times I had a nurse check my heart rate lately. All 3 times we were within 1 BPM. I find my HR very accurate.
