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.

I was on the fence between Ringconn Vs Oura Vs Ultrahuman. I ultimately decided on the UH ring for a few reasons.. 1. Superior temperature and cycle tracking. 2. Easy to use, interactive, FREE to use app. 3. No monthly fees such as Oura ring. This ring is comfortable to wear while sleeping, it tracks sleep best, too. The workout tracking feature needs a bit of work but I have my Apple Watch for that. It charges quickly, and needs recharged about every 4 days (it keeps collecting data even in low battery mode and then syncs to the app once charged). I have never had any issues with the sync not functioning minus when I went out of the country and didn’t have Bluetooth connectivity. A soft reset quickly resolved that issue. All in all, the hardware and software of the ring are super easy friendly for someone not tech savvy, and it’s comfortable enough to wear 24/7 and tracking your health without looking obvious - just a fashion statement to those who don’t look closely. Don’t regret the cost for even a MOMENT!

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.

Love the ring and the product. It does exactly what it says it will do. The ring size kit was worth it, definitely get one of those if you're unsure. Fits perfecting on my index finger. Love the color, the app is easy to use, so far the waterproof feature has been on point and the sleep tracking is very accurate. I have also worn it while indoor climbing and lifting but I tape over it to avoid scratches or damage which was worked; thus the durability has been very good so far.

I recently bought the Ring Sizing Kit and, although I decided not to purchase the smart ring itself, I found this kit to be an essential step in the decision-making process. This company approaches sizing differently than traditional jewelry stores, which makes the kit invaluable. Through it, I discovered that a size 8 was too snug for me, especially considering you'd need to take it off for charging. Meanwhile, the size 9 was too large. Unfortunately, the smart ring isn't available in half sizes, which ultimately led me to hold off on buying the ring itself. Despite not moving forward with the smart ring, I found the sizing kit to be a worthwhile purchase. It's a great way to ensure you find the perfect fit before making a bigger investment. If you're considering the smart ring, I highly recommend starting with this kit to avoid any sizing mishaps later on.

Highly recommend this kit if you are thinking about getting a smart ring. I spent a week switching btwn 2 sizes....wearing over night and all day to gauge natural changes/swelling etc. Decided on a size, got my smart ring and it's the perfect size and comfortable!
