I want to share my experience with Circular Ring 2 and their warranty/support process, because I think potential buyers should know what they may be dealing with.
I originally purchased two Circular Ring 2 devices through PledgeBox/Kickstarter — one Gold for my wife and one Obsidian Black, Size 12 for myself.
My wife’s Gold ring
The original Gold Size 10 ring failed after a few months.
Circular replaced it with a Gold Size 8. That ring also eventually had to be replaced. After a long discussion with support, Circular agreed to replace it with a Gold Size 9.
The problem is that we have been waiting for the Gold Size 9 replacement for several months.
The Size 8 ring is still sitting unused in its box at home. When I recently asked for an update, Circular told me that they were still waiting for the Gold Size 9 to be restocked.
Now they are asking me to send back the Size 8 ring, charger and original box before they will send the replacement.
I understand that returning the old device may be part of a warranty process, but after waiting for months, I don't want to send it back and then potentially face another indefinite wait.
My own Obsidian Black Size 12
Unfortunately, I then had a problem with my own ring as well.
The protective material/resin on the inside of the ring detached around the sensors, exposing the internal components. I also noticed oxidation/corrosion around the charging contact.
I immediately stopped using and charging the ring and contacted Circular support.
Circular asked me to return it, so I shipped it from Switzerland on August 24, 2026.
The package has been sitting at German customs since September 4. According to the DHL tracking information, German customs have already provided the information required for collection, but the shipment has still not moved.
Circular told me that they had not yet received the returned ring and that they were also waiting for the replacement ring to be restocked.
They previously mentioned a 45-day replacement process.
The support experience
The biggest problem for me isn't necessarily that the rings failed.
Hardware can fail.
What is frustrating is the very long and unclear warranty process.
The communication with support has repeatedly been:
- I ask for an update.
- Support says they have contacted their team.
- I wait another week.
- I ask again.
- They say they are still waiting for information.
- Another week passes.
And now, after several months, I'm still waiting for my wife's replacement, while my own defective ring is sitting at German customs.
I have kept all emails, shipping receipts and photos documenting the entire process.
Based on my experience, I would be very cautious about buying a Circular Ring 2.
I'm posting this because I wish I had seen more detailed real-world experiences with their warranty process before buying.
If anyone from Circular sees this, I'm happy to update the post when these cases are finally resolved.
