Circular sucks! It’s horrible! My ring stopped working exactly 2 weeks after I received it and it took 6 months for them to replace it. They barely responded to my emails and they always had a poor excuse as to why it was so difficult to replace. If I could give zero stats I would. They say it takes 2 weeks for the ring to learn your routine but that is also the same amount of time for return status. You can’t do anything while the ring is learning you so don’t really know if it’s properly working or not. This company and ring is awful and I advice people to seek other brands and save money!

Circular: Three Months Without My Warranty Replacement and Growing Concerns About the Product Itself

I was one of the original backers of the Circular Ring 2 because I genuinely believed in the product and the company's vision. Unfortunately, my experience has left me feeling completely let down, both by the hardware and by the company's customer service.

After my Circular ring failed under warranty, Circular instructed me to return the device so that a replacement could be sent. I returned my ring on 4 March 2026 after being assured that, once the return was confirmed, my replacement would be dispatched immediately.

It has now been over three months.

Circular has had my ring since March, yet I still have no replacement, no tracking information, no refund, and no meaningful explanation.

Since returning the device, I have sent numerous follow-up emails. Each time I have received some variation of the same response:

"We're waiting for an update from the team."
"Stock is arriving in 2–3 weeks."
"Your replacement will ship next week."
"Your case has been prioritised."

Yet nothing ever happens.

The timeline is astonishing:

2 March – Circular confirms a replacement will be issued.
4 March – I return the ring.
31 March – I am informed the replacement is out of stock and should arrive in 2–3 weeks.
21 April – I am told it will ship the following week.
5 May – I am told stock is still being replenished and shipments are expected the following week.

Since then, silence.

I have now escalated the matter directly to senior management, including the CEO and Digital Marketplace Director, requesting either shipment confirmation or a refund. That email has also gone unanswered.

At this point, Circular has had possession of my ring for more than three months and has failed to provide the warranty replacement it promised. I have effectively been left with neither the original product nor a replacement.

What makes this even more disappointing is that I was an early supporter of the company. I backed the Circular Ring 2 based largely on the roadmap and promised features, particularly blood pressure monitoring, which was promoted as one of the major innovations that would differentiate Circular from established competitors.

My understanding at the time was that this functionality was expected by the end of Q4 2025. We are now well beyond that date, the feature has not been delivered, and I have seen no clear communication on when customers can realistically expect it to arrive.

As an early backer, this is incredibly frustrating. Early supporters take on additional risk because they believe in the product and the company behind it. In return, they expect transparency, communication and delivery against commitments. My experience has been the exact opposite.

I wanted Circular to succeed. I supported the company early, recommended the product to others and was excited about its future potential. Instead, I have experienced hardware failure, months of delays, repeated broken promises, poor communication and a warranty process that appears completely incapable of delivering a simple replacement.

The technology may sound impressive on paper, but a product is only as good as the company standing behind it. Based on my experience, I cannot recommend Circular to prospective buyers.

Three months without a warranty replacement, unanswered escalation emails, and key promised functionality still missing is simply unacceptable.

Absolute scam, been waiting for a refund for 2.5 years as my ring never even turned up! AI generated emails saying it will refund… avoid at all costs people

Surprisingly good customer service via email. Joana got back to me with a complete, clear explanation that answered my question in one crisp communication.

J'ai acheter une bague en occasion.
Mais l'application ne marche pas, n'arrive même pas à crée un compte.
A fuir cette marque, aucun SAV, ...

Proceed with care. I ordered the ring size like first and came to the conclusion wasn’t for me. Now I can’t get my money back. Customer support is non existent.

I’ve been using this ring for a while now and the experience has honestly been better than I expected. The design feels modern and lightweight, so it’s comfortable enough to wear all day without any irritation or discomfort. One thing I appreciated immediately was how simple the setup process was. The app connected quickly, the instructions were clear, and everything felt very user-friendly from the beginning.What stands out most is how convenient it makes tracking daily health information. I like being able to check sleep patterns, activity, and other stats in one place without feeling overwhelmed by complicated menus or features. The syncing has also been reliable for me, which makes the overall experience feel smooth and polished. Even with occasional small app glitches, the updates and improvements show that the team is actively working on making the product better. Overall, I’m genuinely satisfied with it and would definitely recommend it to anyone interested in trying a smart ring for everyday use.

I’ve been using this smart ring for a short time and I’m enjoying it so far. The ring is light, comfortable, and looks very modern. The setup process was quick and the app is easy to navigate. I like checking my sleep and health details in ace. Everything has worked well until now and I’m happy with the experience.

I’m really happy with this product. It looks stylish, works properly, and is very simple to use every day. Everything feels easy and comfortable, which makes the experience better. So far I’ve had no problems and I’m pleased with my purchase.

I like that it has no subscription fee. I could give a gift to my mother, and took advantage of mother's day promo.

I pre-ordered this ring and waited months for it to be shipped. When it finally was, it never reached me because something happened with the courier before delivery to my house. I sent all the proof requested, but the company initially refused both a replacement and a refund.

After months of constant complaints and follow-ups — and despite repeatedly asking for a refund — they eventually agreed to send another ring instead, after long periods of no replies from customer service.

In the meantime, I bought a ring from another leading brand because the lack of communication made me assume I had simply lost my money.

After months of trying to reach someone for a refund for a ring I never received, they just said they will sent a replacement. The replacement arrived almost one year after my original order (Circular Ring 2 – rose gold version). I wore it for only two weeks and it became heavily scratched all over, while the colour started fading so badly that it already looked years old. I’m not particularly rough with my hands, so this was extremely disappointing.

I contacted customer service again and sent photos. The representative, Earl, insisted this was “normal wear and tear” and said:
“To clarify, the color finish coming off is considered normal wear and tear” and “gentle cleaning and careful handling can help preserve the rose gold finish as much as possible.”

So apparently this level of deterioration after only two weeks is considered acceptable and its expected.

As for the app and insights, they are very basic. The prompts mostly repeat the same information, and syncing frequently fails or misses data altogether.

My verdict: a very low-quality product for a very high price, combined with poor customer service and a weak app experience. For this price point, there are much better alternatives available.

The other ring I bought — which I’ve worn much longer — also has some scratches, of course, but the quality is simply not comparable, and the information and insights provided are far more useful and accurate.

(No affiliation with the other brand — just genuinely disappointed with this product’s quality, customer service, and software.)

I’ve been using this smart ring for a while now and overall I’ve had a genuinely great experience with it. The first thing I noticed was how comfortable and lightweight it feels compared to other wearable devices. It’s easy to wear throughout the day and even while sleeping without feeling uncomfortable. The design also looks modern and minimal, which I really like.
The setup process was straightforward, and the app was simple to connect and navigate. I mainly use it for tracking sleep, wellness, and daily health information, and it’s been very convenient having everything organized in one place. Over time, I’ve also noticed improvements with syncing and overall app performance through updates, which shows the company is actively working on making the experience better.
Another thing I appreciate is the customer support. Whenever I had questions, the team remained professional, friendly, and willing to help. Even when responses took some time, they always handled things politely and carefully. Overall, I’m very satisfied with the ring, the app experience, and the support provided. It has become part of my daily routine, and I would definitely recommend it to others looking for a smart ring.

Worked for a bit then stopped, the companies response was that it needs a rest, done that, worked for 3 days then stopped.

Decent tech but horrendous app.

AVOID LIKE THE PLAGUE

My ring broke after less than a month of wear and despite many backward and forward with support I am still yet to receive a replacement under warranty.

They keep promising to send me a returns label to return my faulty ring and never do and refuse to send me a replacement in the interim. It’s now been 6 months of trying to secure a replacement for my faulty ring and between the huge delays in their response times and the terrible support I feel like I have been scammed when I was one of their original backers when they launched.

DO NOT BUY.

I want to like this ring but after having it for about 6 months, I wish I had bought literally anything else.

Pros:
- Comfortable
- No subscription fees
- Offers great data (when it's working)

Cons:
- Easily scratched. I got the silver one and it was shiny for about 2 days before I noticed it gets scratched on anything at all and becomes a little dull.
- App is absolutely awful. It crashes often, I frequently have issues with syncing, and it doesn't always collect my sleep data. Currently, my app is unable to sync data with my ring without crashing (this has been happening for the last few weeks), so it's basically unusable now.
- Bad glue on ring. The glue on the inside of the band is starting to peel off. This is just an aesthetic thing for me, but if I wore it to swim or shower I'd be worried it'd short out.

I really wanted to love this ring but the non-functional app essentially renders my $400 ring useless. It's worked for the last 5 months, but now it doesn't. I uninstalled the app and reinstalled and it removed all my data and I had to reconnect my ring, and it still doesn't work. At this point I'm considering trashing this one and getting something functional.

EDIT FOR CIRCULAR REPLY:
The app is up to date to version 29.1.4.
The ring is on firmware version 1.4.6.
The app crashes when trying to sync with my ring. It gets to about 72% then the app closes - this happens every time around the same percentage. The app has been uninstalled and reinstalled and the cache has also been cleared.
