I LOVE my FitBit One. We are inseparable. When I started I logged about 3-5,000 steps a day. It really made me cognizant of how inactive I was. I now hit 10,000 steps most days, striving for 12,500 now plus at least one 15,000 step day on the weekend. While I had it shortly before I started 5:2, I kicked in both in seriously in April. Did I mention how much I love mine:) Several members of my family have one and you can form groups so you motivate each other. I have a family group, work group, and friend group. Takes no effort to log, it us all done thru bluetooth on your computer, iphone or ipad. I just checked my steps and I lack 27 from hitting 15,000 today, so I will have to make a circle within my house. I park far away, I circle in stores, march while in the elevator, anything to stay active. I could take some screen shots of my dashboard and post them if anyone is interested. Can't say enough good things. You can order them from Amazon or Brookstone has them in stock.
