I've been testing the Fitbit Ultra recently; it combines data/statistic collection with a geat web interface, an iPhone app and running/general fitness which got my interest.
This past week I've been collecting the statistics to compare Fitbit vs Garmin vs Nike Fuelband vs Nike+. I will be completing a run this week to complete the review and will post up soon. Im also hoping to compare the results in a couple of weeks time head to head at the Nottingham Half Marathon. Not sure any of them will help with my PB though?!
