Pros
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.

Cons
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.
Con Weak vibration causes alerts to easily go missed
The Charge 2 has a very weak vibration that is easy to miss, especially when you're active. As a result, it's easy to miss silent alarms or reminders to get up and move.
Con No smart alarm
Although the feature has been requested by the community since 2014.
Con No actionable notifications / call and text only
You can only see call and text notifications, no Facebook, Twitter, email, etc. And you can only see them, you cannot reply, delete, dismiss, etc.
Con App is not intuitive and terrible on Android
It is clunky and annoying, but works part time. There's a report on another Android that it just doesn't work. No alerts for 250 steps per hour. Not accurate. Clunky non intuitive functionality.
Con No water resistance
It is not water proof or even water-resistant. The watch will still function if you get a little splash of water on it, but you definitely can’t take it if you go swimming,
Con Lower quality screen that scratches easily
Rather than gorilla glass which is commonly used in the more expensive trackers, the Charge 2 fitness tracker uses a thick plastic display screen. It makes the device appear lower quality and scratches very easily.
Con Lavender band turns blue after a short period of wear
The specific color of band can start to turn blue after only the first day of wear. It very quickly looks stained and dirty.
