Oura Ring 4 | Smart Ring | Size First with Oura Ring 4 Sizing Kit | Sleep Tracking Wearable - Heart Rate - Fitness Tracker - Up to 8 Days Battery Life

Product works as expected and is hepful. After 7 months of usage battery is dying, resisiting less than one day after full charged. I contacted the seller, and free replacement arrived in couple of days, no need to return the mafunctioning one. As such, a one star reviewe turned into a 5 stars.

No wonder it is priced very high but it delivers the quality justifying the price tag

After 5 months of usage battery capacity decreased to ~ 1.5 day. Sometimes during the night ring hangs and does not provide sleep metrics at all. This issue also seems to be related to battery malfunction. Latest firmware and soft resets do not help.

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

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.

Color has changed in few months. A lot of scratches. But the ring in overall is very good and functional.

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 Oura Ring colour has tarnished within 4 weeks of wearing, it now looks copper (not rose gold), and doesn't match my jewellery. I'd ideally like to exchange but the return window is really short on Amazon and there is no option to swap now even after a short period, wouldn't recommend as the colours tarnish very quickly!

Delivery took longer than expected, but i am happy with the ring. It does exactly what they advertise. Its a nice to have.

前モデルのバッテリが1日しか持たなくなったため、第4世代モデルに移行しました。機能は前モデルとほぼ同じなので、アプリサイドの更なるアップグレードを期待したいと思います。とはいえ、安定のモデルであることは間違いないです。

Najlepszy tracker samopoczucia i dobrostanu

I’ve only used it for a week so I haven’t gotten the full insights it can offer, but the Oura ring 4 has been great so far. I bought it primarily to track my sleep, and it’s fascinating to track the quality of my sleep each night.
