Ultrahuman Reviews 

Extremely disappointing experience.

My Ultrahuman Ring became unusable in April, and what followed has been months of frustration, repeated troubleshooting, delays, and poor communication. Despite paying extra for warranty coverage, I have spent months without a functioning product.

What I found particularly frustrating was that Ultrahuman repeatedly presented a replacement ring as a gesture of goodwill, when a replacement is something I had already paid to be entitled to under the warranty. Fulfilling a warranty obligation should not be portrayed as a special favour.

Throughout this process, my emails have repeatedly been misunderstood, resulting in two replacement orders being cancelled without my consent. I have had to constantly chase updates and restate my position because it appeared that previous correspondence had not been properly reviewed.

To make matters worse, this has all occurred in the aftermath of Ultrahuman’s recent data breach, which has significantly reduced my confidence in the company and its handling of customer concerns.

I understand that faults can happen, but what separates good companies from bad ones is how they deal with customers when things go wrong. Unfortunately, after months without a working device, repeated delays, cancelled replacements, and a lack of meaningful communication, I can honestly say this has been one of the most frustrating customer service experiences I have encountered.

Software good, hardware just very poor quality. Had 3 replacements. Battery dies every 3-4 months. Now I can’t get it replaced because it’s out of warranty. Guess what! That’s now how danish law works. You get new warranty after each replacement! Their AI is really bad and just creates new support cases.

Unfortunately, my experience with customer support has been similar to many others’. I’m already on my second ring after experiencing a serious issue with the first one, and support has been extremely frustrating to deal with. Responses often take days, and when they do reply, they typically ask for “another 48–72 hours”, only to miss that deadline and require further chasing. Given that I’ve had problems with two rings and received such poor support throughout, both the product and the customer service have been very disappointing.

I’ve had this ring for less than a year and the battery life did not last. I was constantly charging it. I was able to get a replacement after running all their required tests. The second one lasted a few months as it just stopped connecting to my phone. I tried everything to try and connect it. Of course this happened after my warranty expired and they would not send me another one. Also I didn’t pay for a membership so they weren’t going to bother helping me. When the ring was actually working I really enjoyed keeping track of my sleep and other health information. Just a bummer that I wasted over $300 on it just for it to not last. I will be switching to a different brand and not looking back.

Very disappointed with both the product and the customer service.

My UltraHuman Ring has a serious battery issue and does not even last a full day on a single charge. I contacted customer support over a month ago and provided all the documents and information they requested. I received one response initially, but since then I have sent multiple follow-up emails and have been completely ignored.

For a product at this price point, I expected much better quality and, more importantly, much better customer support. The lack of communication is extremely frustrating. As a customer, I should not have to chase support for over a month without receiving any update or resolution.

I am still waiting for someone to properly address my case and provide a solution.

I cannot recommend UltraHuman based on my experience so far.

Support 2/5
Ring 4/5

When I reached the support, it was good...When I reached it.
Even with Ultrahuman X "Priority support", I am waiting 3-4 days for an answer.
I wanted to return the Ring because I found out that this is not something for me, not because of the quality.
I thought about waiting for the 14-day Ring calibration, but now I am very glad I started this way before.
I wrote Support, if the return policy also works if I bought it at a local vendor. Waiting days for support.
Very nice mail back though, and reassured me that it is, of course, possible.
So I answered, asking how I could return it then. Got a new mail, a new ticket number, and have to wait another 3-4 days.
Now I seriously have to see if they even manage to reply to me so I can send it back before the 30 days run out, otherwise I am stuck with it.
I hope the money return won't take 3-4 months...so I am still waiting for the 'how to return it'.

The Ring itself is good quality, even with wearing it constantly, like showering, doing dishes, and sleeping. Only issue is that when you are charging it, it tells you that you didn't move enough, so you should charge it while you are in bed winding down, but not yet sleeping, to not miss out on data.
The plugins sometimes cost extra or are subscription-based, but there are many free ones too, and helpful if you try to find your balance. As I said above, trying it out, I just figured out that a smart ring itself is not something that enhances my life.

Horrible experience, don’t buy this brand! I have been using this product barely for 6 months, first ring stopped working after a few months as the battery only lasted for 1-2 days all of a sudden. I got a replacement, which I was not able to connect with my phone whatsoever, it was a dead product. I got another replacement, which was barely working for a month a and again it stopped connecting with my phone so became useless. I asked for a refund. They keep extending the communication via the email trying to persuade you for another replacement which I made clear I don’t want. After many days of conversation they agreed to send the refund, which never came and no response whatsoever to my email. This company is a scam don’t ever buy from them!!!

I've had the ring for over a month, and the overall experience and customer service has been so bad I wish I hadn't bought anything. I purchased one ring for myself and another as a gift. The first ring arrived broken and didn't work, which took a few weeks to get replaced. After all was sorted and the ring worked quite well, I purchased a second ring as a gift, assuming the incident was a one-time issue. After asking for the plugins I purchased for the gift to be transferred to the gift user (as they had assigned them to my user), they mistakenly transferred all my data to the "gift user". I've been chasing this up for days, with no answers and nobody taking a minute to even reply. I've lost all my data and now the "gift user" has all my data and doesn't even have the plugins I purchased for it. It's an absolute disaster, if I could I'd return both rings and get all my money back, but it's too late now.UPDATE: to make matters worse, the customer service team replied to this and STILL HAVEN’T FIXED THE DATA. All my history was moved to another user so I don’t have it, and the other user has a history that isn’t theirs… zero reading comprehension from the customer support

Not worth it. Disconnects all the time then won’t reconnect. Sent me an old ring to replace and it didn’t end up working. I would buy Oura ring.

I bought an UltraHuman ring in January of 2025. Ring worked great at first, but so short lived. My primary reasons for wanting a ring was to track my sleep due to chronic insomnia. In September, I stopped wearing my ring due to being postpartum and not sleeping well (too depressing to see sleep scores of 12).

In January, I started using my ring again but pretty immediately started experiencing issues. Ring charge would not last, updates would not sync, data was missing. I reached out via the app on three separate occasions with no response.

Finally reached out via email and was asked to try a bunch of things. None of this worked in fact the ring got worse with the resets I was asked to perform. Now my ring is completely unusable. The data that it presents, if any is completely made up (states I am sleeping from 2pm-8pm, etc).

After all of this and months of back and forth, they say that my warranty is now no longer valid and they now state there is nothing they can do. They recommended that I could purchase the pro.

All in, I got 9 months of use ring. Not willing to invest another several hundred dollars on a ring that doesn’t last.

Probably the best customer service I have ever experienced. Like anything, errors happen but any question or concern that I had has been answered and resolved within minutes

I purchased the Ultrahuman Ring AIR in Geneva in May 2026. I started using it on May 4th. On May 24th — after less than 20 days of use — the ring completely stopped working: it lost signal at 30% battery, refused to charge (only showing a blinking light), and never reconnected to my phone. This is a documented, recurring hardware issue across Ultrahuman's user base.
Here's the timeline that tells you everything you need to know about this company's support:

May 24: Ring dies
May 25: I first reported the issue
June 1: I sent a formal complaint email demanding a replacement
June 1: Their response? "The battery drain reset is still in progress — please wait and contact us again." The ring was already completely dead. This response served only to delay my case.
June 4: After days of waiting, they finally confirmed the replacement
June 15: They informed me the replacement will be dispatched between June 19–21
No estimated delivery date to Brazil was provided

That means I will have gone nearly two months without a functioning product that I paid a premium price for — in Brazilian Reais, a very significant financial investment.
The product quality is unacceptable. The support process is slow, bureaucratic, and designed to exhaust the customer. If you live outside of Europe or the US, expect even less accountability. As a Brazilian customer, I was essentially on my own.
Do not buy this product if you live outside their core markets.

Don’t waste your money. Got the ring as a Christmas present and everything was going well until the ring’s battery would drain within a matter of hours after being fully charged and then eventually it wouldn’t charge at all. Wasn’t rough on the ring, don’t even do sports and didn’t even take it into the shower or wash my hands with it. When I contacted customer service they tried to tell me that there was nothing they could do and I’d have to buy a new one even though it was less than a year old. I told them there wasn’t anyway I was paying for a new one, especially since it was less than a year old, and they needed to fix it, so they sent me a new one. However, I placed an order with them for a ring accessory stack to go with my smart ring. That was on April 25th. It’s now June 14th and I still don’t have that order. I’ve reached out to customer service several times but they take weeks to actually answer and when they do they give vague answers telling me that I’ll be sent my tracking information “soon”. No clear answers or deadlines. Customer service is absolutely horrible. Save yourself the trouble and buy an Oura Ring instead.

Completely unreliable information. Battery life is less than advertised. The customer service is literally just a bot that keeps wanting to drain my battery then reset the ring. I’m TTC and hoped this ring would be an asset, but it’s causing more anxiety than it should. 80% of the time it doesn’t read my body temperature, so it doesn’t collect enough data to confirm ovulation. The bot says that if this battery drain and reset doesn’t work, I’ll get a new ring, but after constantly draining and resetting, what is supposed to make this the magical time that’s different??? I’m beyond frustrated with this product and its lack of performance. Only purchase this ring if you like the way it looks, because it’s purely ornamental.

Bought the ring. Registered it, took out Ultrahuman X membership. Ring failed after less than six months and they decline to replace because it wasn’t purchased direct from them.

Nowhere in the T&C does it mention this exclusion, they are just breaching their contract unilaterally at will,

Bunch of crooks, buy an Oura or similar and steer well clear of this dodgy shower of thieves.

It wasn’t bought pre-owned per their statement below. It was new, still shrink wrapped and unregistered. They then charged me £37 to extend the warranty they refuse to honour.

Left if with Amex to sort out for me.

I bought the Ultrahuman Air primarily to track my sleep, so data accuracy was the single most important feature for me. Unfortunately, my experience has been so poor that I cannot recommend this product to anyone.

From the beginning, I started noticing data that was clearly inaccurate. The most serious issue was that the app itself would show that the ring had lost connection for several hours during the night, yet it still displayed detailed REM and deep sleep metrics for those exact periods. If there was no connection and therefore no data being collected, where did those sleep stage values come from? The only conclusion I can draw is that the app is estimating—or outright inventing—data.
There were also many occasions when I knew for a fact that I had been awake during the night, yet the app showed that I had slept peacefully without interruption. After digging deeper and investigating the issue, I found that these periods often coincided with connection losses. That completely destroyed my confidence in the reliability of the data.
After only two months, my original ring had to be replaced. I assumed I had simply received a defective unit. However, just one month after receiving the replacement, I experienced exactly the same issues: connection dropouts, inconsistent readings, and sleep data that simply could not be trusted. At that point, it became clear that this was not an isolated hardware problem but a recurring issue with the product itself.

To make matters worse, customer support has been even more disappointing this second time around. Responses take much longer than the timelines they promise, and as I write this review, I am still waiting for my refund. The only solution they offered was yet another replacement, but after two devices showing the same problems, I have absolutely no confidence left in either the product or the company behind it.
If you are considering buying the Ultrahuman Air to track your sleep, think twice. A sleep-tracking device is only as good as the accuracy of its data, and in my experience, the data is not trustworthy. When an app reports REM and deep sleep stages during periods where it explicitly acknowledges that it had no connection to the ring, all credibility is lost.
I purchased this product because I genuinely needed reliable sleep tracking. Instead, I received unreliable data, two faulty devices, and a frustrating customer support experience. I would not buy anything from this company again.

I ordered my ring in August 2025 and also paid for the two-year insurance policy. Since then, I have received three replacement rings and am now in need of a fourth replacement. Having to replace the same product four times in less than ten months is completely unacceptable and demonstrates a serious lack of reliability.

As a result, I requested a full refund for the ring, the insurance policy, and the additional power plug I purchased, as I no longer have confidence in either the product or the service provided.

I first contacted your team over two weeks ago regarding this refund request. Despite your stated four-day response timeframe, I am still waiting for this matter to be resolved. I have already provided and confirmed my bank details, yet I was subsequently asked to verify them again. I had checked these details carefully before submitting them initially, so this unnecessary repetition has only caused further delays and frustration.

At this stage, I expect this matter to be treated as a priority. Please process the full refund without any further delay and provide written confirmation that this has been actioned. If there are any genuine issues preventing the refund from being completed, I expect a clear explanation and a realistic timeframe for resolution.

Ticket reference: TC-32790

The prolonged lack of communication and repeated delays have been extremely disappointing. I would appreciate immediate attention to this matter and a prompt response confirming that my refund is being processed.

Honestly, don’t even bother with Ultrahuman and go for an Oura..

I have been trying to get an issue resolved since April 2026. My ring was purchased in February of is not working and they tried to troubleshoot it multiple times and realized that it doesn't work, so said they would send me a replacement ring and I am still trying to get that replacement ring. It is well under their 1 year warranty, not to mention that I purchased the 2 year warranty that they pushed for $54.00!! I have been getting the runaround and more runaround from their customer service. All chat bots telling me that my concern has been flagged and that someone will get back to me within 48-72 hours. It is unacceptable.

The Ring is AWESOME, great and tracks everything you need. It’s light and very comfortable. Until you started to have battery and sync issue. As other review here says, they keep asking you to do the same - reset, update firmware- make sure it charging, etc. endless loop slow response. And FYI- I even purchased the extended warranty with replacement included. Been happening for few months on my issue, my tickets been open for 14 days.

Instagram support is perfect. Very efficient and truly attentive to the request.

On the app, depending on the version, it can be hard to find a not AI support for specific issues.

But UH is really paying attention to the feedbacks so I think they’re doing everything they can to improve their service!

Keep going 💪
