ULTRAHUMAN Ring AIR Sizing Kit | Choose from Sizes 5-14 | Sizing Guide for Your Smart Wearable Ring

I was tempted to just guess my size for the ULTRAHUMAN Ring AIR, but I'm so glad I ordered this sizing kit first. The kit includes a full range of dummy rings from sizes 5 to 14, made from lightweight, comfortable material that feels very similar to the actual smart ring. Wearing each size for a full day (and night) gave me real confidence in my choice – something a simple finger measurement or printable guide just can't provide. What I appreciated most was being able to test the fit across different conditions. My fingers swell slightly overnight and after exercise, and the sizing kit allowed me to find the perfect "Goldilocks" size – snug enough to stay secure but comfortable enough to sleep in and remove easily. The kit also helped me realize I needed a different size for my index versus middle finger. The process is straightforward: try on the different sizes, wear them during normal daily activities, and then confidently order your final size online. It saved me the huge hassle of an international return or exchange. For a relatively small investment (often refundable or discounted off the final ring purchase), this sizing kit is absolutely worth it. Five stars – don't skip this step if you want your smart ring to fit perfectly!

This product is amazing. Its been a long time since I received something as useful and of such quality. It might only be a ring sizing kit but I was thrilled when it arrived. The sizes are very comfortable to try on and sit well with other rings. They have a raised point inside to show which way you should wear them. The colour chart is great actually seeing 1st hand the colour options. For the price the box is fantastic ,very sturdy. Arrived next day. Great product if you are considering buying a ring.

Perfect! Found my correct size and I was surprised to see the price was so little for the effort that must go into the production of these sizing kits . So well packaged and get a sense of the accurate feel for the ring when it arrives. Recommend when you’ve finished, look online for somebody to reuse after as it would be such a shame to throw and there is always somebody local who might want to try

Exactly like it says, got very cheap

First class always get your ring sized properly first i did abd it worked.

The ULTRAHUMAN Ring AIR Sizing Kit is a simple and effective way to ensure you choose the correct ring size before purchasing. The sizing samples are comfortable to wear and make it easy to find the best fit for all-day use. A valuable tool that helps avoid sizing issues and ensures the best possible experience with the Ring AIR.

Good for sizing. I think it'd be better to keep and store if the rings could be bunches together.

Great quality, great price

Very nicely packed. Very convenient and light weight. Very useful before buying actual ring. Comfortable. Too many size options. Wear overnight to get used to actual size fit.

Ich habe das ULTRAHUMAN Ring-Air-Größen-Set bestellt, um meine passende Ringgröße zu bestimmen. Das Set kommt in einer schicken Verpackung, was einen hochwertigen Eindruck macht. Es ist praktisch, dass man aus 10 Größen zwischen 5 und 14 wählen kann und diese dann als "echte" Ringe über einen längeren Zeitraum probieren kann ... 🔍 Das Material wirkt stabil und gut verarbeitet. Es ist hilfreich, verschiedene Größen auszuprobieren, um die perfekte Passform zu finden. Ich konnte so sicherstellen, dass der Ring später gut sitzt, ohne zu drücken. 👍 Insgesamt bin ich zufrieden mit dem Set. Es ist eine solide Lösung, um die richtige Ringgröße zu ermitteln, ohne gleich mehrere Ringe kaufen zu müssen oder mit dünnen Drahtringen herum zu probieren. Für alle, die genau wissen wollen, welche Größe sie brauchen, ist es eine gute Investition. P.S.: die "Ringe" sind innen nicht komplett rund, da sie ja einen Smartring imitieren ...

Got this for 1 aed. Packaging alone is quality. Size starts from 5 - 14

Excellent ring sizing kit. Has a realistic plastic ring in each size that you should wear for at least 2 days on your finger of choice. It also comes with a ring colour card to help you pick the perfect colour. I was deciding between this and another brand and this brand was far more comfortable than the other one. I also wouldn’t have correctly chosen my size without this. A few dollars to save myself hundreds and a possible return makes this kit well worth it. Arrived next day so I didn’t have to wait long either. Now I just have to wait for the ring to go on sale 😃

Fantástico! Até agora a funcionar muito bem
