I have two Up bands for sale. The Up band is gray and small, and the UP24 is Pink and size medium. Eat, sleep and move. Better. Track your activity and sleep easy with the UP24 band. Wake up feeling refreshed with Smart Alarm , or receive an Idle Alert a gentle vibration at the wrist when you've been sitting too long. UP24 is your friend-in-fitness wherever you go, 24 hours a day.
