Just the wearable and charging cable. Brand new band, brand new charging cable. I did the factory reset so all you need to do is charge, pair, and workout!! It's also got a watch, Sleep Monitor, Stress Tracking, ECG, Heart Rate Monitor, GPS, Activity Tracker, Water Resistant, Bluetooth Call and Message. Why am I selling it? I got too reliant on the data and let it run my life instead of using the data to understand what my body needs. It's used, and the price reflects it...no warranty. I have charged it, paired it and used it within the past 3 months. I charged it today and then reset it. All that said, I can't guarantee it will work for you. All user docs are available online on Fitbit's website. Fitbit is charging $249. Amazon is charging $199. Both new prices. Others are charging $75-150 used. Check out my price!!
