Customer Reviews Summary

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.
