I have a fitbit one and I love it. It keeps count of all my steps along the day and when I do sports. But I see that when I go to backcountry skiing it can't count the right steps... last sunday more than 3 hours skiing up but few steps registered... why? No differences if i wear fitbit on a necklace (where usually it is) or in my pocket.
I didn't mention it much at the turn of the year, but 2014 was the best year that ever happened to me. Lots of heavy things resolved, two great holidays after an almost 13 year drought and some weight loss success. This year I only have one commandment to follow: do it all better.
