    This is a nice way to stealthily track your activities / sleep without needing something large on your wrist. It doesn't emit too much light, but there is some light you can see from under the ring, but it hasn't bothered my sleeping yet like my watch did.

    Love my ring but bought it too small. Needed to switch to a different finger. But the info I'm getting on my sleep is super helpful. And I like the look of the brushed silver.

    Ive had the oura since March of this year. It does take a couple of weeks to get all the data, but, it’s helpful, comfortable, and does everything you need it to do. You do need a paid subscription for the app which is a reasonable yearly fee. The watches are too bulky. The ring is perfect.

    Absolutely love my Oura Ring! The sleep tracking alone has been a game changer. The insights are detailed, easy to understand, and actually helpful for improving my recovery and daily performance. The design is sleek and comfortable I forget I’m even wearing it. Battery life is excellent too. Highly recommend if you’re serious about optimizing your health.

    Product is great, been wearing it over a month now. I don’t even notice i have it on anymore. I charge it once every 5-6 days, haven’t had a problem with it yet! Only thing I don’t like is the subscription model for this product, otherwise it’s great.

    Very happy with the whole process. Was able to size the ring appropriately for me in the store, and since then I've loved having this insight into my health, especially sleep quality and when my body is fighting some bug. I think the device and app provides a lot more features for women then men, such as cycle tracking, but overall happy.
