Always wear this slim and stylish device and get the motivation you need to get out and be more active. It tracks steps, distance and calories burned and shows you how you are building up against your daily goals. At night, it tracks your sleep cycle, helps you learn to sleep better, and quietly wake you up in the morning. Access your stats anytime on your computer, tablet or from major smartphones, both iPhone and Android. Flex is your perfect companion, it is with you everywhere... even in the shower. It also looks great no matter what you wear. Directions Keep it Clean: Regularly clean your band and wrist—especially after working out or sweating. Rinse the band with water or wipe it with a small amount of rubbing alcohol. Do NOT use hand soap, body soap, dish soap, hand sanitizers, cleaning wipes or household cleaners which could get trapped beneath the band and irritate skin. Always dry the band well before putting it back on. Keep it Dry: While Fitbit devices are water resistant*, it’s not good for your skin to wear a wet band for long periods of time. If your elastomer band gets wet—like after sweating or showering—rinse and dry it thoroughly before putting it back on your wrist. Be sure your skin is dry before you put your band back on. Don’t Wear It Too Tight: Make sure your band isn’t too tight. Wear the band loosely enough that it can move back and forth on your wrist. If you use Fitbit products with Purepulse Heart Rate tracking, for better heart rate readings during exercise, we suggest wearing the band so it’s secure, but not too tight, and wearing the band higher on your wrist (about 2-3 finger widths above your wrist bone). Lower the band on your wrist and loosen it after exercise. Give Your Wrist a Rest: Prolonged rubbing and pressure may irritate the skin, so give your wrist a break by removing the band for an hour after extended wear.
