Oura Ring 4 - Brushed Silver - Size 12 | Smart Ring Sizing Kit | Sleep Tracking Wearable - Heart Rate - Fitness Tracker - Up to 8 Days Battery Life

Amazing! The price was excellent, the quality is great, it tracks my sleep, my meals, my daily activity and it looks elegant and sleek. You can wear it for days and the battery lasts a lot. The best Christmas present!

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.

I was keen to utilise technology to help with my fitness, but love mechanical watches so a smart-watch wasn't an option. Came across this and after some research I gave it a punt. Very happy customer, the ring is a doddle to set up and works a treat. Battery life is a snadge less than advertised but not enough to make me dock points. It's a shame about the subscription, as I think the ring is costly enough that it's something of a liberty to charge for ongoing use, they could lose things like the guided meditation etc and give a free option, or bake in more value-add to the app. Enough moaning though, what it does it does really well, giving me insights into my sleep patterns and broader health. I am happy I bought it and check the app at least daily months after buying.

The app is brilliant. It takes a while to get to know you, so don't expect instant insights, but as it builds a picture it is really good at telling you what's going on. I am using it to track my food etc as well, so not exclusively related to what's happening on the ring. On the ring specifically? Well, it is chunkier than a ring you'd buy as jewellery. That's ok and it's not ridiculous, but you have to get used to it. I do find I take it off and put it on more, or change fingers, as my hand needs a rest. The colour... Despite the name stealth, does stand out. If you want something more subtle then brushed or silver is probably better, as it's more like typical jewellery. That being said, I've gotten used to it. Sizing - definitely get the sizing kit and wear not for a few mins but for a day or two to understand how your fingers change size. Battery life is good. I reckon 8 charge it once every 4 otlr 5 days so far. I understand turning off blood oxygen measuring is the way to really eek out more battery life. You can also use airplane mode to reduce how often it speaks to your phone. But yeah, no regrets, it's a great tool and honestly, easier to live with than a smart watch.

I have used this product and it is genuinely excellent. The quality is great, it works exactly as described, and it is something I was happy to reorder (hopefully I shouldn't have to). The item itself deserves praise and I would recommend it based on performance and reliability. However, the service around this order was extremely poor and it affected the entire experience. My delivery was scheduled for 24 November 2025 between 11am and 2pm. When 2pm arrived, the delivery window changed to 2:30pm. When 2:30pm passed, there was still no delivery. Much later in the evening Amazon attempted to deliver at 7:22pm even though my delivery preferences clearly stated delivery only up to 6pm. Although this review focuses on how good the product is, I feel that mentioning the delivery problems is important because they continue to happen and they create a real bottleneck for Amazon. It was unreliable, frustrating and completely unnecessary. To make things worse, Amazon deleted my original review and told me to edit it, even though they had already removed it and there was no record for me to update. Thankfully I expected this might happen so I kept a copy and can rewrite my honest experience here. In the end I cancelled the order and bought the same item from John Lewis, who usually provide a smoother and more respectful service. The product remains excellent, but the delivery experience and the handling of my review by Amazon were very disappointing.

Tracks biometrics pretty accurately. Has a premium price plus a subscription. Add to the fact that they scratch quite easily it’s not a 5 star. Comfortable to wear, much more comfortable than a watch

This is the second Oura Ring I have owned, this one had a great discount in the Amazon sale so it was worth upgrading from the 3 to the 4. It looks great in Black Stealth and can handle knocks and abuse of a manual labour job. I’ve had it 6 weeks now and worn it every day to work and I still don’t see any scratches dents or marks on it. Battery life is also exceptional at 6 days, maybe 7 at a push. But it doesn’t take long to recharge either. The App that comes with it is very good as well and covers the same matrix that an iOS or Android watch does including sleep, heart rate, oxygen saturation, steps, Activity and even stress. It gives a detailed breakdown of each and depending on how interested you are you can breakdown by day, week, month or year. It can also provide weekly, monthly and yearly reports on All matrix monitored. So if you’re way over your step goal for example the app will suggest setting a higher one. It does the same with sleep etc. There is also a Rest mode if you pick up an injury or illness. I was very surprised when I had the flu and the App notified me that something was going on with my body and suggested rest mode. So if you’re a Sporty individual or just someone like me who likes to keep tabs on my health I would highly recommend this ring.

I discovered the Oura Ring 4 through the Clue period tracking app, and it’s been a total game-changer. I live with Chronic Fatigue Syndrome, Fibromyalgia, and AuDHD, and I was looking for something that could help me track sleep, stress, body temperature, and recovery. Oura delivers on all fronts—and then some. What I love most is the accuracy and depth of insight. It doesn’t just give you only the minimal data, like Deep, Light and REM sleep, but also things like how long it takes you to get to sleep (latency) and how restless you are —it then translates this into genuinely helpful feedback, like sleep and recovery scores, body temperature trends, and guided breathing for stress. The daily readiness score helps me pace myself, which is essential when managing fatigue and sensory overwhelm. The breathing and mindfulness sessions have been a great tool during flare-ups or overstimulation. A few things to note: There is a monthly app subscription, but it’s reasonably priced for what you get. I also got a month free when I signed up. The app is intuitive and easy to navigate, though some people might need a bit of time to explore all its features—there are a lot, and they’re all useful. It takes about 90 days for Oura to fully calibrate and understand your individual baseline, so the insights get better over time. Buying the sizing kit first is a MUST—you’ll want a good fit for accuracy and comfort. Tagging activities and meals is super simple (if you remember to do it). The Rest Mode is a thoughtful feature for days when you’re sick, in pain, or recovering, though I do wish stress tracking stayed active during this mode. Battery life is solid, syncing is quick, and the ring itself is lightweight and comfortable—even with sensory sensitivities. It also integrates beautifully with Clue for cycle tracking, which adds another layer of helpful data for me. If you're managing chronic illness, neurodivergence, or just want a deeper, more holistic view of your health, I can’t recommend the Oura Ring 4 enough. It’s not just about fitness—it’s about understanding your body, honoring your limits, and supporting your wellbeing.
