This is a great fitness tracker (I've also owned a fitbit, this holds up well to the fitbit) Easy to use and is light weight and smooth on your wrist. Just get the app for your phone and set it up! When you're ready for bed it's easy to switch to sleep mode at night (push of a button is all it takes!) and when you wake up to start a new day just another push of the button! The battery life on this last a few days. Simple to charge, just plug into USB port on your computer. Takes maybe an hour to fully charge.Comes in a nice variety of colors. Blue is a really nice color. This band has a silent alarm feature (vibrations) and if you'd like a notification (another little vibration) to let you know if you have been inactive for a few hours. My only complaint about the band is that it is not adjustable.
