Avis sur la ring 2 après 1mois d’utilisation.

Cela avait mal commencé et direct on s’aperçoit que le service client est inexistant: problème de livraison avec UPS et il a fallu que je galère tout seul pendant une dizaine de jours avant d’être livré. Et 15jours après message du service client “nous prenons en charge votre demande”… bref

Commence l’expérience: les très bons points : la bague est légère et on l’oublie très vite. Les mesures ECG, freq cardiaques et Spo2 sont conformes (mesures simultanée avec des appareils médicaux)

Mauvais points : le cercle du stress , vraiment bof. Les comptage des pas (sous-estime de 20% ce que je mesure avec mon Apple Watch)

Les très mauvais points : le sommeil
Complétement aux fraises => elle m’a même calculer un endormissement à 18h en sommeil profond avec un réveil final à 1h du matin
Et sinon toutes les nuits sont équivalentes le calcul de sommeil profond est complètement faux et surestimé- mesure egalement contradictoire vs appareil médicaux

Résultats
Je pensais me passer de mon Apple Watch pour revenir à des montres classiques et ce ne sera pas avec cette bague là sauf s’ils améliorent très fortement leur algorithmes

Beyond disappointed with the customer service here. My item was faulty after normal use and I followed all instructions to return it promptly. Since then, I’ve been waiting over a month with no proper resolution.
I was told to wait an additional 2 weeks for an update- which has now passed- and still no clear answer. I’ve also been informed there’s no replacement available, yet no refund has been offered.
Communication has been slow and unclear, leaving me without the product or any timeline for resolution.
Just sharing my experience so others are aware before purchasing. Hoping this gets resolved soon.

I have the ring since nov14th '25 - what I can say syncing is finally under control - there is still some glitches in the UI here and there, but that's because it's a startup. The support in case one has issues, is painfully slow, and asking the wrong questions over and over again. But overall the thing does what it's supposed to do. I like it a lot

Crap product, all promises were completely off.

I have reviewed this ring previously - the first time a couple of months after receiving it. At that time I was pretty happy with it but there were definitely issues with delivery and system stability. Even though those issues were resolved, there were new issues - especially missing step data. I even went for one period of roughly 9 days when no activity or sleep was being recorded, and I was about to give up on it when suddenly it started working again...and I have had (fingers crossed) a good experience since. So...to those who say Circular is a scam...I think that is unfair. I am liking my ring now and I believe the company is getting its act together. Give it a chance.

I am beyond frustrated with Circular's "customer service." I was an early Kickstarter backer , but that loyalty has been met with nothing but generic templates and month-long delays. My ring broke during normal use while I was sleeping. It took a full month of constant emailing just to get them to send a return label. During that time, I was told repeatedly that there were "no confirmed timeframes" for anything.After finally returning the ring to their Hong Kong depot, they waited until I confirmed delivery to tell me my replacement size is out of stock for weeks. They refuse to provide a supervisor contact and keep sending the same "patience is a virtue" scripts while I am left without a working device or my data.If you value post-purchase support or your consumer rights, stay away. This has been an exhausting and disappointing ordeal.

Kickstarter backer here. My Circular Ring 2 has stopped working after sitting unused for a few months.

It still charges (light pulses, ring gets warm) but never shows up over Bluetooth in the app or even in a BLE scanner, so it’s completely unusable.

I’ve sent full details, serial numbers and videos to support, and also followed up via Kickstarter, but haven’t had any response for over 2 weeks.

At this point it’s just an expensive paperweight. Pretty disappointing experience so far.

I got the ring to detect exercise induced AFIB only to find out it doesn’t do that if you are moving. I tried to return it the day after I got it because I knew it had a 14 day return limit. When I requested the return I was informed that I couldn’t return it because I had activated it. I’ve never heard of such a thing. So I now have the Circlular ring and I have the Oura ( I ordered it before I was told I couldn’t make my return. The Oura ring is superior and their customer support is great.

In addition to inaccurate health readings such as false readings on Oxygen saturation and AFIB events - CIRCULAR has the WORST CUSTOMER SERVICE. Even though they are "based in France" they run their company like it is a scam. Last Fall, I emailed them over 7 times and never received a response. Today, March 31, I received my first response from them from an email I sent in October. UNTRUSTWORTHY - INFERIOR PRODUCT.

J’ai acheté la bague pendant la campagne Kickstarter en avril. Réception en novembre. Elle a fonctionné jusqu’à il y a 1 mois environ. Depuis impossible de refaire l’association après un reset usine. 0 réponse du support. Pire entreprise française que j’ai vu

Have been in a back and forth fiasco regarding a non functional ring for months no. I am constantly asked to send more and more pictures and videos to them with 0 proof of attempts to remedy the issue have been made.

There "customer service" is likely AI chat bots as it's very circular in conversation and ignores many pertinent aspect of the conversation, despite repeatedly informing it. When asked to have a face to face interaction, they apparently "don't do that"... Doesn't sound human to me.

Either way it's incapable. It's not worth supporting this company unless you want just that won't worth and AI chat bots talking you on circles.

The ring is completely inaccurate about heart monitoring regarding heart rhythm - I bought it because I had AFIB and every EKGI took with it was wrong. Now it has stopped giving me sleep data, despite being charged every other day to make sure that's not a problem and rebooted several times and factory reset once. Nothing works and customer service didn't even respond to an inquiry I sent them asking about the sleep data not syncing.
Poor customer service, glitchy app and inaccurate data on the ring. I wish I had just replaced my Oura instead of wasting money on this ring.

Bought Circular Ring 2 for ECG heart monitoring after my AFib ablation. Total failure: ECG often blank or wrong (vs. Fitbit), missing and wrong sleep data. Support stonewalled refund citing 14-day policy while admitting ring needs 14 days to 'learn you.' They denied a refund and they suggested I eBay it. Do not buy Circular 2!

I would never buy from this company after asking for a replacement ring for size issues. They waited to get back to me and then said the 14 day period has passed and there was nothing they could do. This is after Kira 🍈 informed me it would be taken care of.

If I could give 0 stars, I would. The worst cusomter service I have ever received - or, to be precise, not received.

Received my ring in August and it stopped functioning as it should mid-December. I waited patiently for the situation to resolve initially, because they claimed they had server problems and everything would be resolved 'soon'.

I've been contacting them about the lack of functionality since the beginning of January, and they either don't respond at all, or respond and ask for information I've already provided.

Initially I asked for a replacement, then I asked for a refund because I just don't trust the product any more. They've ignored both requests anyway, so I'm taking legal action now because charlatans like these shouldn't be allowed to just get away with ripping people off.

1 an d'utilisation bilan

ça fait environ 1 an que j'utilise leur bague quasi quotidiennement et je dois dire que j'en suis assez satisfait!
Je m'en sert surtout pour suivre mon cardio et dans la durée, quelques bugs résolus maintenant donc ràs!

The ring failed the plastic inside cracked and expanded making it impossible to put on. Customer service never responded to multiple emails. Product of service not recommended

Full of problems. Customer centre fake and unhelpful. Returns not accepted even for defects. Just avoid.

I purchased the Circular 2 through Kickstarter because its functionality and future potential seemed promising. I particularly appreciated the live metric tracking compared to Oura or UltraHuman.

The hardware itself is technically impressive and sophisticated but the build quality could be improved. My ring cracked internally and chipped, damaging the sensors and causing my finger to be cut. I contacted customer service five times, but only an AI bot responded. This bot directed me to email the team directly. It took five weeks to receive a single standard reply. After a lengthy interrogation and providing proof of the issues, the matter was escalated but I haven’t heard back about who’s handling it or when a resolution will be reached.

My advice is to avoid the Circular 2 until their customer service and backend functionality mature. You’ll be essentially gambling on whether you’ll receive what you’ve been promised.

Well, it would be nice if I got the product in the first place.
Ordered it with the sizing kit during the Black Friday sale because it's really pricey, and though they shipped the kit super quickly arriving after just 2 days, when I opened it the product inside wasn't a sizing kit. It wasn't even a Circular product. It was some random junk from a different company and I have no idea what to do with this thing.
Tried contacting customer service several times. At first I thought they might be slow due to holiday season. But it's nearly March now and still no response. I am angry because that was a huge investment to lose.
