Hi.
I just bought this product yesterday, but I am not sure if it is calculating properly.
the steps seem to jump up at times..
here are some examples:
Got coffee thru drive thru, and it jumped up 12 steps.
opened car door and it jumped up 20 steps..
also, hit punching bag for 5 min to test it out, and the steps did not move at all..
is this common???
thanks
