    I’m super happy with the ring. I have had the ring for less than a month. It’s easy to use and I have already gotten very useful information that has helped my wellbeing.

    Purchased as a gift for wife. Very expensive. She lovesit, wears it everywhere, and enjoys the features. She let me see it and wow the quality seemed cheap. Very lightweight with a plastic feeling. I did not like that. Also paying for the subscription to use it is ridiculous. How much more money do you need to make it work. 3 stars due to price and quality. Wife enjoys so it still wins.

    I love the amount of data it tracks… but most times it won’t sync to ever since I got the newer model. I’m actually filling out a warranty claim right now because it’s on my finger and still won’t sync

    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.
