Protrack fitness tracker

Options
Hey everyone! So my boyfriend's mother got me a Protrack fitness tracker for Christmas. So far, so good, but I'm not sure if I need to look into getting a different one (I think I will next year). I have yet to use it for exercising but I'm just trying to find others who have had any kind of expereince with this kind of tracker. Here is one of the links to it:
