ULTRAHUMAN Ring AIR (Certified Renewed) – Smart Tracker for Men/Women, Fitness and Sleep (Sizing Kit): desertcart.co.uk: Electronics & Photo

Review: Life changing Smart Ring - I can genuinely say that this Smart Ring has changed my life in so many ways. The Ring tracks so many different areas including stress, caffeine intake and its effects, shift work, sunlight exposure, exercise etc. The app is seamless and very well laid out, not only provided the data but giving you real tips and advice on how to make improvements. I do not know if the data displayed is 100% accurate but it gives a baseline to work with and the data then shows trends including body temperature and movement during my sleep. I do not wear my Apple Watch Ultra to bed as it is too bulky and needs charging so the Ring is perfect. Battery lasts around four days, but I charge it when not wearing it for weight lifting to avoid damaging it. The Ring feels super high quality and hasn't yet marked despite continued use in a variety of activities. It is also really light in weight so you don't even notice it and is not bulky. I went for the dark grey titanium colour and it looks and feels more premium than I expected. I got the Ultrahuman X subscription with the desertcart offer and is really worth the extra upgrade for peace of mind, also brings a new feel and look about the app with enhanced features. I had to contact Ultrahuman support via the app to help activate the code and they were really friendly and so fast to respond to message through the chat. Cannot recommend this Ring enough, especially at the price an official refurbished one is on their store through desertcart.
Review: Incredible health insights in a sleek, comfortable design! - I’ve been using the Ultrahuman Ring Air for a few weeks now, and I’m genuinely impressed. It’s lightweight, super comfortable (I barely notice it’s there), and the build quality feels premium. What really sets it apart, though, is the depth of insights it gives me. The sleep tracking is spot-on, and the recovery and movement metrics have actually helped me make better choices day-to-day. The app is beautifully designed and easy to understand — it doesn’t just throw data at you, it interprets it in a way that feels actionable. Battery life has been great too; I’m getting almost a week per charge with regular use. I’ve used other fitness rings before, but the Ultrahuman Ring Air feels like a step up — both in comfort and in the quality of feedback. It’s stylish enough to wear all the time, and it’s genuinely motivated me to be more mindful about my health. Highly recommended for anyone looking to upgrade their wellness tracking without compromising on style or comfort!

### ⭐⭐⭐⭐⭐ Worth buying, great smart ring with a free app!
*by T***. on 10 December 2025*

I’ve been using my Ultrahuman Ring Air for just a couple of weeks now and I'm happy to say that I really like it. I like how it works, the insights it provides and the ring itself. The app is very detailed and tracks a lot of information, which I’m still getting used to and learning how to fully understand. Sleep tracking was my main focus and so far it’s been really impressive. The ring itself also does a good job of calculating my steps. I wore my Fitbit alongside it for the first few days to compare the difference and I was pleased with how accurate the ring was. I love the overall design as it’s super sleek and blends nicely with my other jewellery. I’d definitely recommend using the sizing kit before buying. I’m glad I did, as my ring fits well (size 7). My finger does expand and shrink throughout the day, so it can feel slightly loose at some points, but aside from that the overall fit is good and I am able to wear my ring on both my pointer and middle fingers. Overall, I highly recommend buying this! I bought mine during the Black Friday sale, which was a great time to get it as I saved a lot of money in the end!
