Fitbit is a wearable device that tracks your activity, heart rate, and sleep. It can be helpful for people who are trying to get more active or lose weight. However, there are also some disadvantages to using Fitbit.
1) The biggest downside of Fitbit is that it can be expensive. The devices start at around $100 and the replacement bands can cost up to $30 each.
2) Another disadvantage of Fitbit is that it can be addictive. People may become obsessed with their daily step count or calorie intake and end up becoming very unhealthy in their pursuit of fitness goals.
3) Additionally, Fitbits are not always accurate when tracking data. For example, the heart rate monitor may not be as accurate as claimed or the steps counted may not be completely accurate.
4) Finally, wearing a Fitbit all day long can sometimes feel constricting or uncomfortable
