Great idea to get your correct size because of the big investment you;re making
I think the whole idea of the “Air” finger ring and sizing first is the right thing to do. You pick your normal size or one that feels most comfortable for you all day and throughout the night. This way it will give you a true feel for the correct size ring. This is a huge investment and quite honestly I was very impressed when I saw what was sent and how. As you will see from my photos, the ring sizers show on the indicator card enclosed on top that there are several finishes, and then underneath in the box itself are the prototype rings, with a spot inside each one where the part of the ring goes out a bit to mimic what the actual ring would be like. All the finishes all look to be scratch resistance, the color choices are very nice and they also have silicone covers to help preserve the rings, yet not interfere with the accuracy, heart rate information and the over all integrity of the functionality of the rings information itself. I have three things I have some issues with not with the item but for what these are preparing you for. Even though they offer 5 finishes in a large array of sizes as I said with the silicone covers if needed, they don’t have an actual color such as a light pink that for myself as a woman I would love. Also, I guess this is my biggest issue, with NYState take, a ring in my size which is second to smallest at a 6 women’s, I would be paying almost $400. I know you say well for your health it’s worth it but quite honestly, I have a pacemaker for my heart and an iOS watch that also tracks this same information. But for me I happen to think after suffering 2 heart attacks already, this is important. I will follow up when I can find out if I pay this whole amount of my insurance will reimburse me for part if not all. I have Medicare and an insurance from my husband also. Over all I did feel this deserved a 5 star review because I was even nicer than expected.

Essential Precision for a Life-Changing Wearable
The "Why" Behind the Kit Smart rings are not like traditional wedding bands. Because they are packed with sensors, the Ultrahuman Ring AIR has a slightly different internal profile that requires a perfect fit for accurate data. I ordered this kit to ensure I didn't waste time with the wrong size, and I’m glad I did—I ended up being a size 9, though I typically wear a size 10 on my index finger. The Sizing Process The kit includes 10 high-quality plastic ring sizers (Sizes 5–14). Here is my tip for getting the best result: Wear the sizer for a full 24 hours. Your fingers swell in the heat and shrink in the cold. I found that a size that felt perfect in the morning was uncomfortably tight by the evening after a workout. Color Accuracy A unique feature of this kit is that it includes colour samples. Seeing the "Aster Black" vs. the "Bionic Gold" in person is much better than looking at a screen. The gold has a sophisticated matte-satin finish that convinced me to switch my original color choice. Pros: True-to-Life Feel: The plastic sizers mimic the width and thickness of the actual Ring AIR, which is crucial for comfort. Convenience: It allows you to test the fit on different fingers (index vs. middle) to see which is most comfortable for sleep tracking. Credit/Value: (Note: Mention if your kit came with a credit toward the ring purchase, as many do). Cons: Plastic Texture: While the size is accurate, the plastic is obviously lighter and "grippier" than the actual titanium ring, so keep that in mind when testing how easily it slides over your knuckle. Final Verdict Do not skip this step. The Ultrahuman Ring AIR is a premium investment, and this kit is the only way to guarantee you’ll be happy with the fit on day one. It’s a small price to pay for total confidence in your purchase
