Question about Fitbit Versa

Basically, it works very reliably for me. I mainly get errors when I'm riding my bike, because "ghost steps" are often counted. The recognition of floors is also a bit spidery, after a bike ride you have supposedly walked 150 floors a day :-) Extreme situations such as working with a hammer drill or generally everything that exerts short and strong impacts on the wrists lead to faulty recognition. But this is generally true for all pedometers. Otherwise, the Versa counts really cleanly, whether walking, running or climbing stairs.
I've had several Fitbit models now and the Versa is clearly the best so far. Almost everything works as expected, only as a heart rate monitor during sports it is (like all other Fitbits so far) not well suited. At a pulse rate of 125+, the reliability of the displayed pulse rate is very poor. Unfortunately, the chest strap cannot be used.
