    I originally bought this without sizing (I got a size 8 but it was too small)... Exchanging it within the 14 day return period was simple, but if you miss that window you might be out of luck. Definitely get a sizing kit! Gorgeous ring...

    Purchased this for my wife. She loves it. In her opinion, does a better job than the popular "wrist wearable." Feature that seems neat is it told her her vitals looked abnormal and basically predicted she would be getting sick. The next day, came down with a cold. Great product so far, only downside is it gets scratched really easily.
