    Love the Oura 4! After a year with the Oura 3, I finally took the leap to the 4 and I’m so happy that I did. It’s a better fit and longer battery. It’s less bulky and looks more stylish (but it’s still a tracking ring so “improved” doesn’t mean it’s jewelry). Very happy with the 4 - it’s better than the 3, as much as I hate to admit it.

    Bought this for my wife and she loves it! Tracks her sleep and gives her suggestions. Only issue is the battery life is only about half as advertised. Hopeful a new one will resolve this issue

    Best purchase I’ve made thus far! Gives me an insight on how my sleep is going, if I’m ready for the day, and it also allows me to confidently say that my mind and body is feeling much better now that I know how much rest I need!

    Great Christmas present for my wife, she loved it although I was unaware the size is not for the ring finger but for the index finger. Best Buy made it very easy to switch it out for the correct size!

    The ring works great so far. I have seen some scratches but I workout fairly regularly with it and expect a bit of bruising. No complaints
