I just got it last month as a gift from my brother and it is a good , I should say a very good fitness tracker.
Features: It will work about 24 days without charge. It is light and almost weightless. When you wear it you will never feel its there. When you are wearing it you are not needed to enter your pass word because it know that you. It is almost waterproof. Using from last 25 days and not a single complain.
After using 25 days I am fully satisfied customer
And I am fully recommending this product.
Thank you for reading.
Have a good day.
