Life changing if you’re willing to put the work in
I’ve had it for a month now and I can say it really keeps me on track not necessarily health and fitness but more habits and trends. I think everyone can benefit from it. It came neatly packaged and sealed 100% new and after wearing every day I definitely have a lot of small scratches (and I take it off for showering doing dishes etc) but not visible to the normal eye

Outstanding technology
The ring works very well and it is helping to monitor my health, sleep and activity. Strongly suggested. I got my ring the same day I ordered, great service from Amazon

the best investment I've ever made
I love it !! The Oura Ring 4 is a powerful tool for those looking to optimize their health mindfully and without the digital noise of other devices. It’s ideal for anyone who values sleep quality, physical recovery, and overall well-being. I highly recommend it if you’re committed to improving your lifestyle in a smart and sustainable way.

Not happy with this
Super unhappy with this product. The app is very difficult to interpret and isn’t giving me the fitness support I am looking for. In parallel the skin on the finger which I wear it on seems to have reacted and I can’t wear it anymore!

Tracks almost correct - sleep tracking needs improvement though
Tracks almost correct - sleep tracking needs improvement though - I wake up many times and it does not track that so well

Quality not great
After one month charger/ring stopped working and connecting.

READ THIS BEFORE BUYING!!!
I bought the ring at such a high price, assuming that it would improve my health, but this device doesn't work without a subscription; that's a pure scam. Without the subscription, there is nothing you can do on the app!!!! AVOID!!
