Pros
Pro Long battery life
Wearing it continuously, you can expect around 5 days of use. If you only wear it during workouts, it will last closer to a full week. The charger is proprietary, and you simply place the Fit Smart fitness tracker on it and line up the pins.
Pro MiCoach Train and Run app
You can set weekly goals and training plans through the fitness tracker's app. One downfall is that if you have a training plan set in the app, you can't also have weekly goals. Once you have a plan selected, it will sync with your phone so you don't forget when you wanted to workout.
You can also access previous workouts and achievements from the app, along with estimated times for 5k, 10k, half, and full marathon races based on your past running performances.
Pro Easy navigation
There are 3 buttons on-board. The first toggles between battery status, time, and the different training modes. The other two take you through MiCoach and free training modes. These buttons are easy to find, even with gloves on.
Pro Colored LEDs show intensity
During workouts, the LED lights on the side change color to show how intense your workout is. White (74bpm) is none-light activity, Blue is warm up/cool down, green is calorie burn and boost endurance, yellow is intense training and muscle burn, red (182bpm) is short power bursts to develop strength and speed.
If you have a MiCouch workout selected, on-screen you will see an up or down arrow indicating whether you should pick up the pace or slack it off.
Pro Gives you a lot of options for customizing different types of workouts
The "Sport Profile" feature allows you to customize what stats you want to see for each type of exercise. For example, you may want the GPS on for running but not for a circuit workout. These preset profiles save you from having to set up the device each time you exercise.
Pro Gives you custom activity goals suitable for your level
The daily activity goal is a good way to find out how active you really are in your everyday life. Here you can choose your typical activity level from three options and see how active you need to be to reach your daily activity goal.
The time you need to complete your daily activity goal depends on the level you have chosen and the intensity of your activities. Age and gender also affect the intensity you need to reach your daily activity goal.
Pro Detailed reports
The fitness tracker offers excellent reporting including distance, speed, cadence, heart rate (if paired with monitor), ascent, decent, calories, recovery status, and more.
Pro Ability to add training notes
The app allows you to add additional notes to your workouts for better tracking.
Cons
Con Not for casual use
The Adidas Fit Smart fitness tracker lacks any daily activity tracking. Instead it focus is more on workout/running.
Con Ugly design
While functional, the Fit Smart fitness tracker won't be winning any design awards. It isn't something that you'd really want to wear everyday to work.
Con No GPS
GPS is much more accurate for distance tracking than the accelerometer which the Adidas Fit Smart uses.
Con Sleep tracking lacks detail and accuracy
If you are awake for an extended period of time in the middle of the night and then fall back asleep, the fitness tracker may not see the additional hours as part of your sleep.
Con Unattractive and bulky design
The tracker is quite wide and hard to miss, it's not something that can blend in with what you're wearing outside of sport/exercise type settings.
Con Short battery life when using the GPS
With the GPS turned on, battery life goes from around 24 days to 9 hours.
This is likely fine for people who will always have opportunities to charge it after their run. However for anyone hoping to use the GPS for longer activities, such as hiking, that may not be long enough to be useful.
