BestBuy has them or you can get them on line or I believe there may be a link from here. To hear more about it search Fitbit in the message boards. Tons of posts on this gadget.
In a nutshell it is a slim pedometer that measures steps, miles, stairs, and calories burned plus sleep if you get the One. A Zip is just like a pedometer without so many bells and whistles. I hook mine to my bra and forget about it. I have it linked to the fitbit site as well as SP. the zip is around $50 and the one is closer to $100. They will also be coming out with a wrist band soon.
