Super Helful
The Ultrahuman Ring AIR Smart Ring Sizing Kit is simple, well-designed, and very effective. The rings feel close to what I’d expect from the actual product, which made it easy to find the right size with confidence. I appreciated being able to wear the test ring for a full day and overnight to make sure it was comfortable during daily activities and sleep. The sizing process was straightforward, and the kit arrived quickly and neatly packaged. Overall, this kit removed any guesswork from ordering the ring and gave me peace of mind before making the final purchase. Highly recommended if you’re planning to buy the Ultrahuman Ring AIR.

Helped me realise that a ring tracker felt weird when using dumbbells so I decided not to get one. Saved me a few hundred quid, so that's a win I suppose.

Check if style & likely size of ring is available!
Sizing kit was great, but wish I'd bought it elsewhere. The actual range and size of rings is limited on the Argos website so I ended up having to buy it elsewhere, which meant that I couldn't use the £10 discount code!

The best ring ever
[This review was collected as part of a promotion.] I love the fit of this ring! They send you out a measuring ring size kit with multiple basic ones to test for a day to get the perfect fit! It tracks stress aswell as sleep and heart rates! I love the scoring system it does too! I never understood the value for money after testing this and it’s top of the marks

A great tool for health and fitness tracking.
[This review was collected as part of a promotion.] I have found the Ultrahuman Ring to be extremely helpful with giving me insights into my health and fitness. The ring looks great and is lightweight but sturdy. I am happy with the battery life, not had any issues with losing charge. Overall I highly recommend this, it helps with my motivation to get fit and healthy

Connectivity of the ring is extremely poor
[This review was collected as part of a promotion.] I was really excited when I first got the Ultrahuman Ring AIR. It looked great, felt comfortable, and the app experience seemed promising at the start. Unfortunately, that excitement didn’t last long. Within just two months, the ring stopped connecting to my phone altogether. I tried all the troubleshooting steps, even reinstalled the app several times, but nothing worked. It’s disappointing because when it functioned properly, it gave me useful insights into my sleep and recovery. Now it’s just an expensive piece of metal sitting on my desk. I really wanted to love this product, but the reliability just isn’t there.

Sleek & Fashionable Daily Health Tracker
[This review was collected as part of a promotion.] Been wearing this ring daily for the last month and it has become my new favourite health tracker. I mainly use it for sleep tracking as wearing my Apple Watch to bed was cumbersome. It is very comfortable throughout the day and due to the friendly ring sizing guide you get before the ring, is a perfect fit, battery life is great with several modes to choose from and is very durable for everyday use. If, like me, you are a gym goer or are very active with your hands, it would be best to buy a silicone protector for this as it will scratch under heavy use. The only negative with this ring is a potential flaw its long term functionality, when I first received the ring, it lasted less than 24 hours before it would no longer connect or charge. Upon reading online this is a very common issue with these. Support is not the quickest, with long time in between replies. After being told to try several troubleshooting methods including a 4 day battery drain, which did not work, I was sent a replacement. I was without a ring for over 2 weeks which was a little disappointing but the main thing is that the replacement is going on strong.
