No complaints here. Bad reviews must be fake

No idea why the bad reviews. This little gadget makes almost everything cheap. All the features of the app work well with information overload. Came with instructions and quickly paired with my Android phone. Some just need time to load to complete the required data like sleep. The group is fine and had no problems last year. Connects directly to a USB port. i love this shop To get all these features, it will cost you twice as much. My only complaint is the plastic screen cover, which scratches easily with normal wear and tear.

Pros
  • Sports & Fitness
Cons
  • Out of fashion
