I love my FitBit... More so than my BodyBugg that I used to wear. I had a BB and I wore it daily for over a year, but I got sick of the monthly fee.. I looked into a Fitbit, and thought, heck for $99 I might end up saving myself some money!
I started wearing it last November, and I wore both my Bugg and the FitBit for about a month. I'll tell you that the FitBit wasn't as accurate, but it was only off (on the low side) by maaaaaybe 20-50 cals a day. To save $8 bucks a month or whatever, I'll take it, and that savings has paid for the FitBit already. With it being that small of a margin "off" I'm good. And in all reality, no tracker will be 100% correct, so I'm good with knowing a rough estimate of what I burn. I like that it tracks my steps, and my flights of stairs, and it pushes me to go just that much farther.
I like that I can clip it to my bra strap and no one knows its there, while the bugg was SO big on my upper arm, people would ask me all the time what it was.
One of the best purchases I've made to help myself on this journey!
And I agree with Lock, google google google. I found a wealth of info about it out there!
GL!
