But you don't address the real issues with the Inspire 2...the fact the sleep tracker is sporadic at best in recording sleep stages, the random adding and removing of steps, and the awkwardness of tracking calories.
I agree with the other comments they should work on accuracy, stop calling movements steps, sleep tracker only works when it wants apparently I take 60 to 200 steps in my sleep. I can sit and still get 10000 steps a day it's easy to THINK your fit with one of these.
