Black Fitbit Charge with charger Silicone band (L) fits my 7" wrist with room.to grow Works great. Just need to download the app on a smartphone. Tracks steps, weight loss, calorie intake, calories burned, heart rate, stairs climbed. Will track you while you walk with the app on the phone. You can set goals on the app. I really loved using it but now have a Samsung watch otherwise I would not sell it.
