I saw a post .. I think on the Band Support site about doing a soft reset to eliminate some of the inaccuracies. I for one have had ZERO issues with the heart rate, calories burn, pedometer etc.. it is IMO very accurate.. I have verified by manually check my pulse using a garmin GPS and comparing workout calorie burn estimates via MFP and it is pretty spot on..
I guess I'm not seeing all the "issues" unless you mean comfort or some such.. AFA using the device it has worked beautifully for me. I don't see a need at this point to have a separate food intake and tracking outside of MFP. But that is just me and I block googles ads in my browser so the site work quite nicely
FWIW.. I work out pretty much everyday (Insanity) so it's not like I'm Paul Thurrott measuring my heart rate doing 12 oz curls
(all due respect to Paul) Just sayn
