Pro Replaceable wristband
The tracker itself is a separate part from the wristband that can be taken out and put in a different band.

There are even custom bands available from third-party vendors.

Pro Adds a social layer
Information regarding goals and progress can be shared with friends, and users can even challenge each other with goals.
Pro Progress towards a goal is indicated by LED lights
There are 5 LED lights that, after double-tapping the wristband, display progress towards a goal. Each light indicates 20% progress towards the goal and the tracker allows choosing between steps, calories or distance to display this way.
Pro Quick food and drink logging
Because of Fitbit's database of foods' nutritional information, food and drink logging is easy.
Con Oversensitive pedometer
The step counter often counts movement unrelated to walking or running as steps. It ends up reporting more movement than has actually happened.
Con Hard to get the tapping right
The double tap to activate the LED display lights must be the appropriate pressure and timing in order for it to work correctly. This can be frustrating to some users.
