Review: Best bit of health kit I’ve bought! - Completely addictive, so interesting in terms of the info - I’m debating moving away from my Apple Watch as the battery on this is so much better - I always charge my watch overnight but the sleep info on the Oura is great, amazing accuracy on the patterns! The battery life i would say isn’t quite as long as described but still a few days so good enough! Super easy to set up and use, debating the travel charge case but at the moment not sure it’s needed as the charger is just USB C. Definitely worth ordering the fitting measure, I wouldn’t have had a clue but annoying when you decide you want to go for it as adds a few days before you can purchase. Once bought though a perfect fit. I bought the brushed silver and have had quite a few compliments, it’s a really nice, non flashy piece that blends well with other items of jewellery. Expensive but so far I would say worth it :)
Review: Great Product - Best health tracking product on the market. For measuring activity, stress and sleep it really is brilliant. The app is easy to use and very intuitive. Battery life is good, only charge mine for 5-10mins per day, whilst showering. Good durability, I wear it all the time and only small surface scratches are visible.

### ⭐⭐⭐⭐⭐ Don’t know where I’d be without my Oura
*by R***N on 12 May 2026*

Don’t know where I would be without my oura ring! It’s so interesting to know all the data about sleep, heart health etc. If you’re thinking about getting one, let this be the review that gets you one! Very, very convenient. I don’t wear my Apple Watch anymore as I’m a nurse and can’t wear watches. Would say that this is more accurate and better. Its tracks fitness, steps, sleep, women’s health etc. It also helped me conceive which I’m very grateful for. It is ‘bulky’ but you do get used to it! I often speak very highly of this product and got atleast 5 people to get one. I don't know where I’d be without my Oura ring
