  • Sleeker design
  • Waterproof
  • Comfortable to wear
  • Long battery life


  • Limited to basic exercise tracking
  • A fiddly clasp
  • Basic notifications can be improved


While The Fitbit Flex 2 is a commendable upgrade from the original Flex, it is still a rather basic fitness band model in comparison to the competition. The improvements are noticeable and discernible with the waterproof capability taking the day. The ability to use the tracker in all situations including the shower and the pool is an added advantage. The addition of the smartphone notifications is also a good touch. The Flex 2 is however not all that and cannot fully serve a fitness fanatic to the maximum. If you are a fitness newbie or just looking for some basic activity tracking, then the Flex 2 is a gadget that should be on your wrist right now.  But for the sports fanatics that require everything from a fitness gadget, then this may not be the best alternative for you.

Fitbit Flex 2

The Fitbit Flex 2 is an upgrade from the Fitbit Flex. The Flex was little more than a basic tracker that provided the Fitbit users with all the fundamental basics of activity and sleep tracking. It, however, did not go any step further beyond that. The Flex 2 is a device that has been brought more up to date adding some of the much-needed features that the competition was boasting of like waterproof capacity and some basic smartphone notifications.

Key Features of Fitbit Flex 2:

  • New, slicker design
  • Automatic exercise recognition
  • Waterproof to 50m with lap counting
  • Smartphone notifications
  • All-day activity and sleep tracking
  • Interchangeable bands and accessories

Product Description for Fitbit Flex 2:

The Fitbit Flex 2 is 30% smaller than the previous model, with a much narrower band that is comfortable to put on. The bands come in a wide range of color which include navy, magenta, black and lavender making the buyer spoil for choice. The bands also have a textured finish making the easier on the skin with prolonged wearing.

The Flex 2 also has some similarities to its predecessor, with the button clasp still in play. This makes it a bit cumbersome to put it on upon removal. There lacks a loop for threading the strap through making it a little tricky to fasten. The Fitbit Flex 2 is however not limited to the wrist alone; it also has a pendant accessory to allow for placement around the neck. This, in turn, requires you to give up sleep tracking and Smart track functionalities.

The Flex 2, just like all other Fitbit produces, come with the ability to pair with both Android and iOS devices via Bluetooth. This enables you to sync your activities with the app. The application allows you customization over your notifications from other apps like SMS, Facebook, and even WhatsApp.

The SmartTrack feature automatically kicks in during different forms of exercise like cycling, running, swimming and even longer-duration walks. The swim tracking, however, needs to be manually enabled before it can start working. When it comes to running, you have to settle for the lack of a GPS and as such you are unable to keep track of your distances. Unlike other Fitbit devices, the Flex 2 has no altimeter. The battery life is however quite impressive, going up to one week without charging.
