This Fitbit Charge 3 is an activity tracker designed for individuals who prioritize running, jogging, swimming, exercising and 24/7 heartrate tracker. It has a sleek, waterproof (2 sizes Sm/Lg) gray band and rose  colored sides. This model is ideal for those looking to track their fitness progress accurately.  My husband bought this for me and I've never used it. I signed up for an account and deleted/cleared it. It comes with charger.
