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

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

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.

Ring 4, ~3 months old, iPhone 16. Disconnects at least every 1–2 hours; when it happens, the app/phone can’t find the ring until I place it on the charger (charger LED turns on immediately). Completed soft reset + factory reset + full re-pair (forgot device in iPhone Bluetooth) — issue persists. Battery now drains within a single day. Please check diagnostics and advise warranty replacement if hardware/battery issue is suspected.

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.

I hesitated for a while before investing in this gadget. And I love my Gadgets! but after doing some homework on the competition, I decided to jump for it. First, the fit and metal colour are great, I couldn't be happier, the quality and durability is insane, i do everything with it, I rarely take it off. The connectivity to my Samsung Z Fold6 was flawless, no hiccups, plus, everything you open the app, it updates in no time. so great compatibility. Now, you need to give it time to gather data about you, of course... it will not happen overnight which is quite right, but the intel you get afterwards is great. Your body age, sleep quality, energy available, your stress, it is such a great little ring. it is a lot of money for such a small device but the value for money is worth it. I highly recommend it if you are curious and want to be nudge in the right direction for better health.

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.
