    Love my Oura ring! I got the rose gold two months ago and still looks nice. I like it better than my Apple Watch. Great purchase

    Love this! I had been looking at it for some time, then finally chose to buy! Wish I would have bought earlier. I was very worried about scratching as I had read of difficulties on some reviews...mine is holding up just fine!

  • Wanted to love it but didn’t :(

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I wanted to love this ring, but unfortunately, I didn't and returned it within 48 hours. I had to buy the size to fit securely so it would read accurately but anytime I went outside or got hot and my hands got swollen, the ring got extremely tight and uncomfortable. It also bothered me a lot at night due to the bulkiness. It would also give me a really good sleep score when I woke up multiple times and tossed and turned all night. So I didn’t find it to be that helpful and that is the primary reason I bought it. I do have several friends that love it though! Just wasn’t for me.

    So far so good, Sizing I'm still up in the air on. I did sizing in store and was advised to go a size up for finger swelling, but most of the time the ring is pretty floppy on me. The ring has quite a bit of scratching on it and haven't had it very long.

  • Great but not worth the monthly subscription cost

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I like the ring; however, the cost you pay along with the monthly subscription is not worth it. If you have an Apple Watch, you are basically paying a monthly subscription for the additional data that is nice to have, but not worth the cost.

    This ring replaced my first generation Oura ring. My two adult children also have rings and we are in a Circle so we can offer encouragement and congratulations depending on the readings.

    Amazing technology and amazing ring. Is someone tells you that for less than a $500 investment, you can live 10-15 more years. Would you do it? Well that’s what this ring can provide.

    I had the Gen 3 but decided to upgrade to the Gen 4 for the recessed sensors. I also changed from silver to stealth. Overall a good decision to change.
