[This review was collected as part of a promotion.] I bought this in April and have worn it everyday since, really enjoy the sleep and cycle data this provides. And no monthly subscription! For anyone looking to purchase highly recommend, and fit wise make sure you can wear on multiple fingers to account for size fluctuation’s when it’s warm etc..

[This review was collected as part of a promotion.] I bought my ring 4 months ago and I have mixed feelings. I love how light and sleek it is. I get compliments on the look of it all the time. I prefer it over wearing a watch. I love the sleep insights and all the data it collects. However, my one con is that the battery life is terrible. It took a while for the ring to calibrate to a place where the battery lasted a few days on a full charge but now after 4 months post-purchase I had to get a replacement because the battery dies within hours after a full charge. For the price, I would hope the item would last way longer.

[This review was collected as part of a promotion.] I bought this ring two months ago and it has helped me alot from finding out why im still sleeping and when is the best time to consume coffee. I wish the charging was faster but you can't have everything. I'm using it also to track my cycle good investment. I do wish it was not so easy to show the scratch marks.

[This review was collected as part of a promotion.] I bought the Ring AIR less than a year ago in December 2024 and I’ve been extremely satisfied and impressed with the insights available, especially sleep. However, in recent weeks, the battery life has absolutely diminished and I struggle to get through a single day without charging once or twice.

[This review was collected as part of a promotion.] I got my ring in December of 2024 so that I could track my health and my cycle. The cycle tracking is favorite feature. I also really like the sleep tracking. It helps me identify things that hinder my sleep. Overall the ring helps me understand my body better so that I can treat it better.

[This review was collected as part of a promotion.] I recently purchased this ring for the sole purpose of improving my sleep and overall health. I do have an Apple Watch as well but find that I can easily sleep with the ring on and do not notice it at all. The health data it collects is extremely accurate especially for sleep! I have been able to make some changes to my night time routine based on suggestions from the app and have improved my sleep. The battery is great and holds up well, I often only charge it when I shower and have never gotten a low battery alert. I can wear it for the entire weekend without charging it which is nice if on vacation. The only reason I gave it 4 stars vs 5 stars is that I found the gold to scratch very easily. Although you can’t tell until you close it’s unfortunate as only a couple months old.

[This review was collected as part of a promotion.] I got my wife an Oura ring. She wanted me to have a smart ring too and I picked the Ultrahuman because I hoped it would help monitor for a-fib and also because I didn't need a monthly subscription. It seems to track sleep as well as the Oura and costs less, so that's a win. Unfortunately, the a-fib detection wasn't available in the US yet. The caffeine window feature is nice, reminding me when to stop drinking caffeine and to delay in the morning.

I bought my Ultra Human ring in April, and while I love all the insights and the look of it. I have two issues with is, the first is how easily it scratches. I always wear a silicone cover over it while lifting weights but even during everyday it gets more scratched each day. And second is the battery life, its advertised to last for 4-6 days but really it only lasts for 3 days. I have tried chill mode but still the advertisement does not align with its battery capabilities.

[This review was collected as part of a promotion.] I’m absolutely impressed with this smart ring! It’s sleek, lightweight, and incredibly comfortable to wear all day. The tracking accuracy for sleep, heart rate, and activity is spot-on, and the battery life is excellent. I love how discreet it looks while still giving me valuable health insights. Syncing with the app is smooth and user-friendly. Totally worth the investment – highly recommend it for anyone who wants smart features in a stylish form!

[This review was collected as part of a promotion.] I have used the ring around 6 months Pros: - Lightweight & Comfortable:Only 2.4 grams with a titanium build, ideal for 24/7 wear and sleep tracking. - Accurate Health Data:Detailed sleep stage analysis, HRV, and body temperature monitoring with practical recovery insights (e.g., optimal caffeine intake timing). - No Subscription Fee:More cost-effective than Oura Ring, which requires a monthly subscription. Cons: - Limited Fitness Features:Not ideal for weight training, lacks GPS, and relies on phone syncing. - Complex App:Data-rich but has a steep learning curve, with occasional sync delays. Best For: - Users focused on sleep and stress management. - Those who prefer lightweight, subscription-free health tracking. I think it is excellent for health monitoring but niche in functionality—best suited for specific needs.
