It made the whole process so much easier and gave me a lot more confidence that I was choosing the right size the first time. Since these rings do not match standard ring sizing exactly, having the kit was definitely worth it. The instructions were simple to follow, and I liked being able to try different fingers to see what felt most comfortable. I ended up wearing the sizer for a full day like recommended, and I am happy I did because my finger size changed a little throughout the day. That helped me avoid ordering a size that would have been too tight. The sizers themselves felt comfortable enough to wear around the house, sleep in, and even while doing everyday tasks. I also appreciated that the kit included a full range of whole sizes so it was easy to compare fits side by side. This is a smart little purchase that can save a lot of hassle with returns and exchanges later. If you are ordering an Oura Ring 4, I would definitely recommend getting the sizing kit first. Review: Seems accurate. Don’t use on sweaty fingers. - At first I was a bit scared with this ring sizing set because the rings don’t slide smoothly on the fingers and wasn’t easy to take off because it was kind of stuck to my skin instead of sliding off easily. I usually wear a size 5.5, but since there’s no ".5" size, I tried a size 6. It is worse if you have a sweaty hand or your hands is wet. My family tried them too and had the same problem. But when I tried them with very dry hands, they were not that difficult to take off. They are very thick and sturdy. It will definitely last a while. And the sizing seem quite accurate. ## Features - Find the Right Fit Every Time: Our ring sizing kit compatible with Oura 4 ring size , makes it easy to measure your finger and find the perfect size before ordering — ensuring comfort and accuracy for you or your loved ones. - Easy to Use：Our finger measure for ring size simply follow the number on the card to perform the fitting test.
