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!

We purchased the Oura Oura Ring 4 as a Christmas gift for our 20-year-old son, and it has quickly become one of his favorite gifts. He’s very interested in understanding his body better, and this ring gives him exactly that without being bulky or distracting. The first thing he commented on was how comfortable and lightweight it is. Unlike a smartwatch, he doesn’t feel the need to take it off during the day or while sleeping, which makes it much easier to wear consistently. The sizing kit was definitely helpful, and once the correct size was selected, the fit was spot on. What really stands out is the amount of data and insight the ring provides. He loves being able to monitor things like sleep patterns, activity levels, recovery, and overall wellness in one place. The app presents everything in a clean, easy-to-understand way, making the information useful instead of overwhelming. It’s more about trends and awareness than obsessing over numbers, which I appreciate. Sleep tracking has probably been his favorite feature so far. He’s been genuinely surprised at how detailed the sleep insights are and has already made small adjustments to his routine based on what the ring is showing him. It’s encouraging to see technology used in a way that promotes better habits rather than distractions. Battery life has been solid, and charging is quick and simple. He also likes that it doesn’t constantly buzz or demand attention—it quietly collects data in the background and lets him check it when he wants. Overall, this was a great gift and feels well worth it for someone interested in health, fitness, and self-awareness. If you’re looking for a wearable that focuses more on wellness and less on screens and notifications, the Oura Ring 4 is an excellent option. Our son absolutely loves it, and it’s something he uses every single day.

I've had my aura ring for a little over a month now. I was very hesitant about this purchase. For one it's one of the more expensive options for tracking biometrics on top of that you need to pay a monthly subscription to really use the thing. That being said it is worth every single solitary penny without a doubt. This thing gives you easily comprehensible data on pretty much everything from the very moment I'm typing this to long term trends. Sleep, fitness, vitality, stress, resilience and so much more. It's also a great educational tool providing you with tips and feedback along the way helping you reach your goals to become a healthier and more productive version of yourself. Here's an example of something that surprised me; this ring started reading and warning me of symptoms of illness before I really started feeling sick with the flu. It diligently kept close watch on my vitals and advised appropriately. It's been extraordinarily helpful in balancing effort with recovery so I don't overdue thing and also don't become complacent. I'm still learning new features and aura is still developing new features all of the time. If you're serious about tracking and improving your health and fitness this is the most useful tool I have found in changing my life second only to faith. The investments you can make in yourself having this much data and sound advice at hand is worth far more than the cost of this ring and subscription. If you have fingers you'd be a fool not to purchase this.

Love the Oura ring is not true to normal ring sizes so definitely use a sizing kit! Becomes comfortable as you wear it an get used to it. I feel like it tracks the heart rate and sleep well but maybe a little less accurate on the activity. Super easy to set up and use the app but does come with a subscription charge. Waterproof I do dishes and shower and everything with it on! But does scratch very easy.
