Customers Say
Ultrahuman Ring offers accurate health and sleep tracking, comfortable fit, sleek design, and good battery life. Sizing kit is helpful, but some users report app issues, limited fitness tracking, and durability concerns.

Good tracking
[This review was collected as part of a promotion.] Great device for those who are interested to track daily habits and especially when going to gym and tracking training goals. Can easily connect to my phone, easy to use when it comes to tracking heart rate, blood flow. Besides helps location capture and additional biomaker data. It's perfect tool to track your health and understand it's needs. Lightweight and great design

Fine at sizing, don't expect your money back.....
Great from the perspective of sizing, but states you can get your money back when ordering the ring you need from Argos, but the code expired 6 months prior to our purchase! Plus Argos didn't have the size we wanted anyway. Got the ring from the Ultrahuman website...... Where they also send out free sizing packs.

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.

Expired code
Item spot on but discount code Argos provides for money off the actual ring have expired. Wouldn’t buy again

Useful
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
