    The new version of the Oura Ring (4) is much more comfortable than the 3! It pairs beautifully to wear everyday and the insights are so on point. Recently I woke up just feeling off and the app told me that it detected changes. It also is spot on with my cycle, the sleep and readiness score are super helpful. I’ve owned an Oura for almost 3 years. Recently got the newest version and it is completely worth it.

    Absolutely love this ring! Great quality although the metal does show scratched pretty quickly. Oura also has excellent customer service- they’ve sent me a new ring when my problem couldn’t be fixed online.

    Overall very happy with the product. I prefer having a ring over a wrist wearable and it provides tons of interesting "lifestyle" data. Not sure how happy I'd be with the product if I were looking for a true fitness tracker. Cons: - The "pink tax"--rose gold looks better on my complexion and paired with 18K gold jewelry I wear, but the quality IS NOT worth the extra $150 over silver, which I had before switching to this color. - Lots of great data, but can't easily identify drivers or patterns across the many metrics. It would be great if its AI could bridge this gap to help draw deeper insights on your data. - Battery lasts long enough, but not as long as the company claims

    Great ring. Is not heavy at all and doesn’t look bulky in your hand. The oura app give all kind of good data about your sleep, heartbeat rate and temperature to keep you healthy. It does charge you 6 dlls for the app subscription but totally worth it. It does scratch easily so wear a cover if you plan using it during workouts and weightlifting

    Love this ring, it truly lives up to the hype centered towards to and does exactly as it says. Couldn't have been happier with this purchase. Depending what you do, I would suggest getting a case just in case, but other than that, it is a remarkable product.

    Love this ring, tracks sleep, workouts, walking, and even tells me when I am starting to get sick. Only removed one star because it scratches extremely easily when weight lifting and I recommend that they sell some type of guard for us active gym people lol
