Got my fitness tracker in Two days!! It paired really easily to my phone once I downloaded the app for the fitness tracker. Instructions are easy to follow and helpful. I like how slim it is and that the band has multiple holes to adjust the wacth... I have small wrists so this was a bg deal. It tracks all my steps and my running and how many calories I burn in a day. Then it resets for the next morning. I real really loved that it came with TWO chargers!!!! I keep one in my car and one on my desk at home. Great Watch!!
