    Much better sleep data and overviews than fitbit. Comfortable. Battery life is good its refreshing not to wake up and realize you missed sleep data because the thing died.

    Love it! I’m still learning what all it does. Keeps up with my sleep which is why I bought it. Helps me keep up with my sleep apnea, my steps, my stress levels and a whole lot more. Even tells me when I’m sick before I know it. Very happy with my ring.

    Once I was able to get the correct size it’s been great! The longer you wear it the more intuitive it gets which is nice. It’s also very comfortable for wearing while sleeping!

    Loved this ring so much over a fit but I used to have and Apple Watch. It gives you so much information regarding your heart health and especially your sleep health. I’m so sad that I lost it, but I will be buying a new one!

    Better than I expected! You select a focus personalized to you so you are getting information tailored to your goals. The reminders are subtle and targeted. The battery life really lasts 1 week! The only downside is the small scratches on the bottom of the ring but they cannot be seen unless you are looking.
