I am in love with all the functions of the tracker, the color, and the 3D graphics. It is so awesome. It also holds a charge for 5-7 days when fully charged. I want to purchase one for my hubby. I think he would definitely take the fitness more seriously with this tracker. It is more than words can describe to me. It connects to your phone, you dont miss calls or messages. For me, and I have had 4 fitness trackers, this is the 1st one I am in love with.
