Fitbit Charge Wireless Activity Fitness and Sleep Tracker Wristband Large Black This fitbit was used for approximately 6 months. Works like a charm. Only selling as I have an upgraded watch. I will say that although the charger works completely fine,it can be a bit finicky to keep the charging cable on the wristband itself. As long as you have a flat surface to charge then there wouldn't be any problem. Once fully charged the fitbit can last between 5-7 days before needing to be recharged. Included: Fitbit Charge Black Large USB Charging cable Wireless sync dongle Instructions for Setup: {url removed}
