User reviews

Insupportable ! App trop bugé, pertes de données récurrentes

En 3 mois c’est-à-dire 5 ieme fois que l’app crash lors de la synchronisation bague app. Les données stockés sont toutes perdues. Faut revoir le code de votre app c’est n’importe quoi

Et je ne parle meme pas du manque de fiabilité des données notamment cardio, lorsque je compare avec ma montre garmin j’ai toujours des énormes différences

Lack of Technical attention

Since I purchased the ring, it only registered sleep data one night, and due to calibration process. Despite of my continued requests p for technical attention, and after sending them all the data they requested, no technical support was received, and the ring is yet defective: if the sleep data are missing, many of the features won’t function, either. I have sent them about 20 email and messages, and yet, no solution given. Caveat empor.

Still complete rubbish

Absolutely appalling product and disgraceful customer service.

The Circular app is complete rubbish, the ring itself is unreliable, and the customer service is virtually non-existent. It took six months just to receive a response, followed by another three months of endless back-and-forth, with no proper resolution.

Despite the ring clearly being faulty, Circular has refused to replace it. Instead, they repeatedly ask for the same information and data that has already been submitted multiple times. It feels like a deliberate attempt to delay, frustrate customers, and avoid taking responsibility for a defective product.

The health and sleep metrics are wildly inaccurate, the ring constantly disconnects and reconnects, and the connection issues make the app almost unusable. Trying to track a workout or sporting session is an absolute joke. Most of the time, it either fails completely or produces data that cannot be trusted.

This is easily one of the worst products I have ever purchased and one of the worst customer service experiences I have ever had. Circular should be ashamed of the way it treats paying customers.

Do not waste your money. Do not trust the metrics. Do not expect support when something goes wrong. Avoid Circular at all costs.

BUY AN ULTRAHUMAN OR OURA. Great product and very accurate metrics.

Terrible Product

It worked for less than 2 weeks and then it wouldn’t stay connected, they say the battery charges in 30 minutes and last up to 7 days that’s cap, I charged it for 30 minutes it died the next day. The information it provides is also inaccurate, and they will not let you return the ring after you use it and find out it doesn’t work. Do not buy this ring.

Deceptive

I purchased this ring during their kickstarter phase under the promise of blood pressure monitoring (the entire reason I purchased the ring) and other benefits.

To date, a year later, there is still no blood pressure monitoring and at no point has my ring properly tracked my sleep regardless of restarting the ring, syncing first thing in the morning and last thing at night, etc.

I purchased the gold ring and it’s tarnished and easily scratched as well.

I’m deeply disappointed in this ring and wouldn’t have wasted my money had I known it would be this unreliable.
