Ring 4 Sizing Kit - Size Before You Buy The Oura Ring 4 - Unique Sizing, Not Standard US Ring Sizes - Receive Credit for Purchase

I purchased the Oura Ring 4 sizing kit because I didn’t want to guess on sizing for a $300+ health device, and I’m very glad I didn’t skip this step. The sizing kit is well-designed and closely mimics the look and feel of the actual ring. Oura recommends wearing a test ring for at least 24 hours. Still, I found it helpful to wear mine for several days to account for normal fluctuations in finger size (sleep, activity, temperature, etc.). This made a noticeable difference in choosing the correct size. One of the biggest benefits is accuracy. I typically wear a size 7 in rings, but after testing, I found a size 6 fit best for the Oura Ring. Without the kit, I likely would have ordered the wrong size. The fit of the actual ring matched the sizer exactly. I also appreciated being able to test the ring during real-life conditions. I wore it during work shifts that involved frequent handwashing, hand sanitizer use, and repeated glove changes, and it held up well. That gave me confidence in both the sizing and the practicality of wearing the ring daily. Another advantage is saving time. Purchasing the sizing kit separately allowed me to determine my size right away and order the ring without waiting for the standard sizing process (which can add a couple of weeks). For anyone eager to receive their ring sooner, this is a helpful option. The kit includes a small credit toward the ring purchase, which helps offset the cost slightly. While the kit itself may seem expensive for what it is, the value comes from avoiding sizing mistakes and delays. Minor note: the sizer felt slightly bulkier/heavier than the actual ring, but not enough to impact sizing accuracy. Overall, this is a practical and worthwhile step if you’re considering the Oura Ring, especially if your ring size varies or you want to be confident in your purchase before committing.

This sizing kit is a great idea if you’re considering the Oura Ring. It helps you test different sizes and get a better feel for the fit before committing to the actual ring. I ended up returning it since I didn’t move forward with the purchase, but the kit itself was easy to use and useful for figuring out sizing. Definitely recommended if you want to be sure before buying the ring!

Great sizing tool for Oura, and I think for general ring sizing too. The sizing ring is a little thinner than the ceramic version, but it’s a good tool for sizing and to make sure you choose the right finger.

Great to find the right ring size before spending a lot of money!

Gifted. Person thought it did help with determining size needed and getting use wearing it. Claim is that you get $10 credit when purchase the ring itself. Box even has a QR code to do so. Didn’t work to scan. Didn’t default when purchased either. Had to contact customer service, took quite a while. Rather a waste really, there is no use for the kit once you purchase the ring. Just wasted plastic.

Such a great idea. I’ve been wearing an Apple Watch since 2020. I’ve loved being able to track my sleep and steps, but the battery is sadly not living up to what it used to be. I’m really wanting a smart ring for a better battery life. Before making such a large purchase, I love the idea of being able to be very confident in the size.

I got the Oura Ring 4 sizing kit to figure out my correct size before ordering the actual ring, and it definitely served its purpose. The different sample sizes made it easy to test what felt most comfortable throughout the day and even overnight. That said, once I found my size, I wasn’t really sure what to do with the kit afterward—it just kind of sits there. It would be nice if there was some kind of return or reuse option. Overall, it’s helpful and pretty much necessary for getting the right fit, but not something you’ll have much use for after that.

Works fine

後で判明したがアマゾンとその他で1000円近く値段が違う。類似の商品にも出て来なかった。 ２４時間装着とあったので着けて寝たら、かぶれでしまった。本商品とは素材が違うが、高いので怖くて買えない

Great sizing tool. However, Amazon SG doesnt allow the actual Oura Ring to be delivered. The status has been “Ordered Received…”
