Fitbit with charger - not sure if sensor is 💯 working

Stay on top of your fitness goals with this sleek smart fitness tracker. Featuring a stylish white band, this wearable is perfect for tracking your daily activities and health metrics. Band has some white marks. Charges fine. However, I’m not sure if the sensor is working at 💯 as it didn’t seem to be counting my activities properly. If you’re handy and can fix it, then that’s wonderful! Check out the rest of my closet to bundle and save on 100s of items!
