    This was a gift for our sister-n-law and she is very happy with it. She was telling us it tracks her sleeping habits and heart rate which is what she was wanting it for.

    Works great and does much more than I expected. I would order a half size up from the ring you typically wear.

    It’s great! I wanted it to track my sleep mostly and it’s been very accurate. However, it is easy to scratch if you gym but we bought silicone covers off Amazon and it works fine.

    I love the Oura ring. Went from the 3 to the 4 and although it’s very similar the 4 is more comfortable. I love the information it gives and how it helps me improve aspects of my life

    I've had my oura ring for 2 months now and really enjoy it! The app itself has so many insights and I love knowing what my readiness score is everyday. I got the silver because I didn't want to spend the extra on the gold and bought a pack of silicone ring covers on Amazon for like 10 bucks and it helps with the scratching + I can wear different color if I wanted. Really recommend!!!

    I liked how it gave me data but end of the day disliked gotta pay for it. I bought for my husband and I got him wrong size and they didn’t wanna exchange it for the correct size and wanted me to pay another 100$ on top because of it so I said nope and returned the item. Overall data is nice to know if u have issues
