It's the device's inability to provide an accurate measure from start to stop that is a gap for anyone serious about exercising. There's no way easy way to track time and distance on the FuelBand. Nike says it sells other Nike+ accessories that can complement the device, but at $149, I expected the band to do more.
Nike wants you to buy into the concept that Nike Fuel points will become a new standard measurement for activity. Given that it uses the Nike name, I doubt Reebok or Adidas will be jumping on this bandwagon.
Few people are going to know or care what Fuel score you earn on a given day. So it's really up to individuals to determine the value they place on this score. For me, I found it useful as a general guidepost for activity. Prior to getting the FuelBand, I was slowly getting back into a regular exercise routine, so I found it a great motivational tool.
I've had the FuelBand for nearly a week, and I'll admit I've exercised more in the last few days than in the last few weeks combined. I set my daily goal for 3,000 Fuel points, what Nike defines as a fairly active day. It actually took a good amount of activity to hit that mark, and I was able to exceed it only by running, playing tennis, and hitting the gym on three consecutive days. On the days when I didn't exercise, I fell well below the mark.
A run in Central Park, for instance, garnered 2,500 points, while an hour of tennis earned about 1,000 points. Because the points are accumulated by the movement of the wrist, scoring can get a bit wonky. Cyclists who keep their hands on the steering wheel may get no points for their effort. On the flip side, I earned nearly 400 points by sitting at a bar and drinking beer (lifting mugs is hard work, after all).
The color LEDs on the FuelBand serve as an extra crack of the whip: the lights move from red to green as you approach your daily goal, taunting you to keep moving until you hit your mark. When I was a few hundred points away from the goal, I spent the last hours of the night walking around my apartment to boost my score (your Fuel score resets to zero at midnight).
Overall, as a measure of activity, it can at least give you a clearer picture of whether you actually are exercising, or just staying in the office and working, which got me a score of just below 2,200. One issue: it's difficult to change your daily goal, which can only be altered after you exceed your preset benchmark.
Battery life was satisfying. Nike rates the FuelBand for up to four days of run time between charges. In my experience it exceeded this, lasting six days before it needed recharging, and that included regular syncing with my iPhone plus constantly looking up my score.
The $149 FuelBand certainly isn't for everyone. Despite Nike trotting out a few superstar athletes at the , I doubt many hard-core fitness buffs will find much use for it. For runners or cyclists, there are a lot of other, more useful devices, including gear that incorporates GPS and can more accurately keep track of time and distance. For example, the $249.99 Motorola MotoActv may be a better fit. Still, there are a lot of people who could benefit from such a motivational tool, and the trophies, banners, and color charts from the Web site and app do go a long way toward spurring a less-than-athletic individual into changing up established patterns. A less expensive alternative is the simpler, $99.95 Fitbit Ultra, which also offers activity tracking in a tiny package.
