Buyers Beware!
I decided to opt for the Ultrahuman AIR after comparing the price to the aura ring. The HUGE price difference between the gold option from each brand, and the lack of a monthly subscription, made me choose the Ultrahuman. Unfortunately, I only got ~3months out of my first ring before it completely died. It could sit on the charger for hours without ever responding. I purchased the protection through the Ultrahuman app because it was expensive enough that it felt justifiable to me. I worked with customer service to try troubleshooting and ultimately got a replacement ring. I thought that maybe I had purchased a defective ring. Welp. That was not the case. The second ring lasted for a few months and died exactly like the previous ring had. If the price of this ring was not so much, I would’ve given up and moved on. Nevertheless, I worked with customer service, again, to replace the SECOND ring. Don’t get me wrong, when the ring works, it is really awesome. I love the app features and health insights. I have had my third ring for ~6 months now and it still has moments where it does not connect to the app, even though it has full charge. I really wish Ultrahuman would address this issue because I have seen countless reviews stating that this is a huge problem. Please consider my experience before purchasing this ring. I can’t help but feel like the aura ring is more expensive for a reason. I really love this ring when it’s actually working, but geez. I had really hoped to get years out of this device. Unfortunately, it’s a big no for me.

Have been using several months and really like its integration with Apple Health and FreeStyle Libre system. Good insights. Also tried Oura and didn’t learn nearly as much with that system and Ultrahuman doesn’t require a subscription. 2 year warranty extension is fair.

Very profesional
[This review was collected as part of a promotion.] Excellent product. I am using for almost 2 years and had huge positive impact over my health and knowledge in different points about sleep and hygiene in terms of my sleep.

Do not buy
Not even 24 hours into using the ring it stopped connecting. I tried everything to connect it again and I have been directed to drain the battery which will take about 5 days. Not even sure if after that it will reconnect. Extremely disappointed.

Worse purchase. Even Target won’t help and let the customer suffer. My Ring stopped pairing with my phone and Target said that it is out of return window and they couldn’t help.

Cheap - terrible customer service
Don’t buy this ring. I bought one for myself and one for my mom. You have troubleshoot this ring everyday. Sometimes it doesn’t even give you insights on your health score. I’ve reached out to customer service and all they ask if it’s updated. Yes it’s running on the newest update. Battery life is trash, you’ll have to charge it everyday. Don’t buy - please just buy the Oura ring. I wish I did.

Waste of money
I’m so disappointed. The ring stopped working as of 12/31/25. It will not connect to my phone and the chat is clearly a bot. I would not buy this again.

This item is defective. Target is sold out and Ultrahuman will not replace as they are not allowed to ship to the US anymore. DO NOT BUY THIS PRODUCT!

Almost perfect
Here’s the deal. I love this. Until it stopped working. I’ve only had it for 3 months and I just had to deal with customer service because the battery stopped lasting and it won’t connect to my phone anymore. Customer service is a huge pain in the butt to deal with. As far as features go I love it. I’m giving a 4 star because I really do love it. I just wish customer service was better.

Don't buy
Absolutely don’t buy. They shouldn’t even been selling this in the U.S. Bought for my daughter for Christmas. Didn’t work right out of the box. She can’t get it to pair to her iPhone and there is no light like there should be. Contacted customer service and she was told they can’t support her because of a lawsuit with Oura. The website says it’s not available in the US so why was I able to order through Target.

Excellent sleep and cycle tracking!
[This review was collected as part of a promotion.] I've been using the ring for over half an year now and Im super happy with it. The activity tracking for sports could be better but since I tend to use a sekretem device for this im not too bothered. Sleep tracking is excellent but I think cycle tracking was the biggest game charger for me. I never rememberd to track my cycle and now that ist done pretty much automatically I've started connecting my symptoms to my cycle and discovered my healh issues are due to perimenopause. The data collected made it so much easier to advocate for myself with my health provider! No subscription is also key here!

If you are looking to purchase this ring, be sure it is what you want and you have the correct size. I am sure this is a great ring however if anything is wrong, it is not returnable. My advice would be to order direct from Ultrahuman.

Got other wearables before
[This review was collected as part of a promotion.] I used many other wearables in the past, but was impressed by the Ultrahuman Ring Air. A big plus for me was its affordable, subscription-free price. Initially, it was the practical form factor that attracted me, and pairing capabilities with the most popular smart watches and iOS and Android phones. Easy to wear, fashionable, super light, and comfortable to wear all the time. No need to remove around water, thanks for being waterproof. I discovered a new world of advice on better health and well-being. Impressed by the sleep, stress, cardio reporting, AFIB, recovery, and brain age, stress management data, and amused by the accurate caffeine window. Not perfect but improving daily, with WhatsApp 24/7 customer service when needed.
