Fitbit?

Betty B got it right - I love my Fitbit Flex (the one without the watch).  The only thing better than the Fitbit Flex is the Fitbit Aria (scale).  I step on it first thing in the morning and via the wifi in my home it records my weight and BF%.  I love having the record of my weight.  Bottom line is that I would purchase both again if something happened to them!!

I have a Fitbit One. I clip it in the center of my bra every day. Love it! I got mine on eBay too, so I didn't pay $100 to get it. Love that as well.

I bought the fitbit flex (bracelet) and just returned it. I tried it for several weeks but it wasn't motivating me because the app wouldn't update and tell me my info. It doesn't like iphone 4's and I'm not buying a new phone. It would only update randomly. I had it linked to my fitness pal, so I will just keep using that for now.
