LOVE LOVE LOVE my smart watch!!!! It has so many great features and it is so sleek and sexy. The magnetic, stainless steel band ensures a proper fit. I was worrried about that before it arrived because my wrists are so small, but it is perfect! It even fits my husband's wrist and his wrist is huge!! I appreciate being able to accurately monitor my heart rate as well as my sleep patterns! It is even able to distinguish my light sleep from my deep sleep! I had no clue how little deep sleep I was actually getting! This little gem is a great tool to help me track my wellness.
