Size: Sizing Kit
Style: Made in India
Color: Sizing Kit
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.

Item is great so far although I just received it yesterday. The box was half open but the ring seems fine. I’m writing this review prematurely just to say I ordered the sizing kits for both the Oura 4 and Ultrahuman Air. I got both on sale on Prime day including both sizing kits prior to ordering the actual rings and I just want to say between the two, on the same exact finger, I’m an 8 in the Oura and a 7 in the Ultrahuman but that being said, when I received the actual rings, the Ultrahuman fits tighter and is less comfortable. I never tried the Ultrahuman app because I’m sending that ring back. I got them both in rose gold and I like the Oura best and it’s more comfortable too. The Ultrahuman is not only tighter but it has a more sharp / less curved edge on it. I think it feels tighter due to this bump out it has inside. I’m also not as fond of the brushes role gold finish. It is a bit lighter though and has no monthly subscription like the Oura but the Oura also synced with my Apple Watch health app. Hope this review helps

Came in like 12 hours. Seriously, i ordered it the night before and was here before i woke up. Not standard ring sizes - not even the same as other smart ring kits- so def try on a few before dropping 350. I havent bought one yet, but ouras sizing kit runs about 1.5 sizes bigger with the bumps inside. UH Air fit me better and the material was much more comfy on my finger, but its not the same you will get in the real ring. UH fit my index finger best at size 8, while with oura i went with a 9 (only bc i want to sleep with it and i couldnt get it off in the morning. That freaks me out bc you cant cut titanium off if your finger swells for any reason). Im usually a 7 on my ring finger, but while a 6 fit me at times, an 8 could get stuck at the wrong time of day. Almost went with a 10, but it got way too loose throughout the day. Very interesting, i know. Just slow your roll and get the kit before you jump the gun. Otherwise, i would have ordered a 7 from jump and wouldnt be as happy with it.

Worked as expected. This is a sizing kit for the Ultrahuman Air Ring. These are molded to be the exact same dimension and size as the real rings so you know exactly what you are getting when you drop the 300 bucks on the real thing. This worked great.
