    Wanted to gift the ring but was unsure of what size was needed. This is a perfect solution. You buy the sizing kit and get a coupon for the amount of the kit. It essentially costs nothing and you ensure you get the right size.

  • Wanted to love it but didn’t :(

    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.

    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

    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.

    It’s just “okay”. I don’t see the value in having it, especially if you have an Apple Watch. Also, the ring scratches very easily … the paint comes off easily.

    Wonderful for tracking sleep metrics. Not as good for exercise tracking. Overall comfortable but takes time to get used to the thickness. Glad I made the purchase.
