New Vivosmart - Very inaccurate

ceit1776

I just got a new Vivosmart today. So far I am not impressed and I am considering returning it, but I wanted to check and see if it is something I am doing wrong first.

I have been wearing my old fashioned pedometer to compare accuracy. They started out on the same number and after about 6 hours of use, the Vivosmart has 3684 steps on it and the pedometer has 8197. I get that they are worn in different places and that there will be some discrepancy between any two devices, but the pedometer is counting more than double (I manually checked it and it seems to be accurate). When I do manual tests on the Vivosmart it is all over the place!

Secondly, while I was cooking dinner, the vivosmart gave me an inactivity alert, so after dinner I packed up the kids and walked to the park with them, played, walked home did some laundry and other house chores and it has not budged. It is currently on 3 hours and 43 minutes of inactivity.....

Am I doing something wrong? Do I have a lemon? Is this just what to expect from the Vivosmart?

Thanks!
