Super Helpful and Accurate Sizing Kit
This RingConn sizing kit made the whole process so much easier. The set includes all the sizes from 6 to 14, and each ring is clearly labeled and comfortable enough to wear around for a day to test the fit. I really appreciated being able to try multiple sizes before ordering the actual ring—it took all the guesswork out of it. The kit is simple, accurate, and exactly what you need to make sure you get the perfect fit the first time. Definitely worth it.

Great first step into buying a smart ring
Works like it should for a sizing kit. Able to size every finger with ease.

Worth fitting first!
Definitely take the time to use the sizing kit. You aren't sizing a normal ring. You want to correctly size this ring because of the multiple sensors. A normal ring (that doesn't have a mount or stone), can spin on your hand and you don't know it. You want this ring to fit well enough that the sensors don't spin from the palm side of your finger. The ring kit allows you to try several sizes, over a day or so, to get exactly what will work best for you, including being in water, or wearing gloves. I actually kept wearing mine after I did order my ringconn, so it would help my finger (and brain) adjust to wearing a ring. I felt like the ring actually is smoother than the ring fitting kit. 👍

Calidad y precio
The RingConn smart ring is lightweight, comfortable, and easy to wear all day. It tracks sleep and heart rate reliably, with especially useful sleep insights. Battery life lasts several days, which is very convenient. The app is simple and clear, though it could offer more advanced features. Overall, it’s a great value for basic health tracking in a discreet design.

Sizing kit fits a tad more snug than actual ring conn
I thought the size 10 size in the sizing kit fit a little more snug than the actual ring conn 2 size 10 however when I received my ring conn 2 it fits it's just a tad bigger than the sizing ring. I think it's due to the different material from the sizing kit vs the actual ring size

More than one size may fit the same finger, you need to wear them for a while before choosing.
Great way to determine your correct size. There were two possible sizes that did fit, but only one was comfortable after wearing for a time. You have to wear them for about a week to know what is really comfortable.

Cheap, just buy it
For the price it is a good idea to just buy this sizing kit. That said you could just measure your fingers and use an online tool to find the ring size. Also an alternative if you have a 3D printer, RingCon supplies the necessary files to print sizers.

Buen producto
Muy buena compra, para saber la talla del anillo de la marca, que te puede quedar bien y pedirlo con certeza. La calidad es muy buena. Contento. Lo recomiendo antes de comprar un anillo RingConn Gen 2

Si lo quieres para medir y devolver, olvídalo
Se tarda mucho en llegar y una vez que llega, te lo pruebas y dices “pues lo regreso, ahí dice que se puede” y si, se puede, pero lo que no sabes es que el envío corre por tu cuenta y amenos que quieras mandarlo por correos de México y darle la bendición, mejor olvídalo, que el envío sale más caro que el mismo producto. Ya tire el mío a la basura

Super hilfreicher Artikel
Ich bestelle häufig Wearables und Gesundheits-Tracker — und dieses Sizing-Kit gehört definitiv zu den hilfreichsten Zubehörteilen, die ich je gekauft habe. 🔍 Größenbestimmung leicht gemacht: Das RingConn Sizing Kit macht es super einfach, die richtige Ringgröße für den späteren Smart Ring zu finden. Gerade weil smarte Ringe wie der RingConn Gen 2 nicht wie normale Schmuckringe sitzen (Sensoren innen, andere Form), war ich unsicher, welche Größe ich brauche — dieses Kit hat mir das zuverlässig beantwortet.  ✨ Qualität & Verarbeitung: Die Ringe im Kit wirken stabil und angenehm im Material – sie lassen sich gut über den Finger schieben und sitzen so komfortabel, dass man die passende Größe schnell erkennt. Für jemanden, der online bestellt und nicht vorab messen kann, ist das ein riesiger Vorteil. 📏 Breite Größenabdeckung: Mit Größen von 6 bis 14 deckt das Kit wirklich viele Fingerformen ab und spart Frust bei der Bestellung des eigentlichen Smart Rings. So konnte ich sicher sein, dass der endgültige Ring weder zu eng noch zu locker sitzt.  💡 Fazit: Ich würde dieses Sizing Kit jederzeit wieder bestellen — es ist ein kleines Investment, das große Unsicherheit nimmt und letztlich dafür sorgt, dass der smarte Ring perfekt passt. Absolute Empfehlung für alle, die sich einen Smart Ring zulegen wollen!
