The screen on the FuelBand lets you check your progress throughout the day without needing to plug the device into your computer or sync to your phone to see your data. Fuel points (which are based on movement) are calculated the same way for everyone, so you can compare your daily activity with others. Once you install the Nike+ Connect software on your computer and create a Nike+ account, you can set a daily goal for daily 'NikeFuel points,' the brand's way of measuring physical activity. A short video on the Nike setup website explains how to get started using the device, which is a much easier way to familiarize yourself with the device than reading a user manual. The Nike FuelBand is intuitive and user-friendly. The other version with a black, rubber covering gives the screen slightly more contrast and makes it easier to read. And the transparent covering made the screen (which has white lights) a little hard to read in daylight. The lack of rubber covering made the device slightly uncomfortable to wear. The device comes in several styles my version was slightly transparent (so you could see the interior of the device) with no rubber covering. And if you're not used to wearing wristbands, you might find such a device a little bothersome (as I did). Still, the lack of a truly adjustable strap meant that the band did not fit snugly on my wrist. I thought this was a clever trick that would save you from having to order a new device if you happened to misjudge your size.

The FuelBand comes with two extensions (called links) that can be added or removed to make the band a smidgen (8 or 16 millimeters) bigger or smaller.

But if you bought a size that's slightly too big or small, don't worry.
