Given that the Fitbit one requires clipping on to something or to be worn using a very uncomfortable Velcro arm band, I’ve been clipping it to my belt. It has fallen off and temporarily been lost twice – and yet found – both times in hotel parking lots unscathed. Today, it happened a 3rd time in a downtown area. I do believe it is likely gone forever. What will be interesting to see is if somehow makes tonight’s or tomorrow’s report back to Fitbit.com (which nonetheless pings here as well.) I think something that small and that easy to lose should not cost 99 bucks. I guess I might consider the Microsoft Band although it does not have an altimeter.
