Not tracking steps or distance correctly?

[LocoMutant]

So I'm using it on the treadmill and I noticed compared to my fitbit One the blaze is way off on the steps.  I;m right handed and wear it on my left and have it set for non dominant hand.  So I did an hours on the treadmill and it's over 3000 steps off.  I counted my steps for a minutes and it's 146 the fitbit only registers 105 steps so for evey 10 minutes I'm off almost 450-500 steps then my normal pace for for an hours it's off 3000 steps.  The distance I did on the treadmill was 4.6 miles and on the fitbit it shows 3.1 miles.  I even used the treadmill setting.  

I regret getting this item and will probably send it back and just use the one.  The only issues is I got it through my works get active program and got it for $136.  If I send it back I want my reward back and I want to use it for the aria scale which was $63.  Buyer beware!

Are you holding on to the hand rail? 

This may prevent the Fitbit from seeing arm motions that look as if your running.

No I don't hold on to the rail.

My Blaze is not accurately tracking my steps.  My Flex tracked very well, but the Blaze shows 1 step for every 5-6 I take.  I am wearing it on my non-dominant arm and have it set to non-dominant.  Any suggestions?
