I bought a Fitbit. A charge HR. Back in January.
I loved it.
Then it started counting random flights of stairs.
One day it gave me a medal for counting over 100 flights of stairs. The same day it recorded 52 flights on my log. 
I get that the actual step counter might not be 100% accurate. If I wave my arm around it often records steps, but that is fair enough.
A flight of stairs is defined by an elevation of 10 feet. My arm is not that long. So waving it around does not come close to a flight of stairs.
I complained. They sent me a complimentary replacement.
It is doing the same bastarding thing. Only with added not counting active minutes.
AIBU to simply expect it to do its job? And work accurately??
I've complained again but won't get a response until tomorrow.
