This fitness tracker is a great tracker . It does so many different things . It monitors my heart rate , tracks my steps, and it also lets me know when I have in coming calls . This device is very comfortable and stays charged for long amounts of time . It is very easy to work and figure out . Also very easy to read and get information from . The band is adjustable , so I can wear it only either arm and just adjust it to fit . I very impressed with the tracker and it works a lot better than some of the other ones I have had . I received this tracker at a deeply discounted price in exchange for my honest opinion.
