Perfect Fit! Excited to Get My Ultrahuman Ring PRO - The Ultrahuman Sizing Kit is well-designed and makes finding the right fit incredibly easy. Size 6 fit perfectly on my index finger, and I really liked the ring's size, feel, and overall comfort. I wore the sizing ring continuously for two days to get a realistic sense of how it would feel throughout my daily activities, including sleeping. Absolutely no complaints! I'm switching from my Oura Gen 5 and have now decided on the **Ultrahuman Ring PRO in Gold, Size 6**. Can't wait to get my hands on it! A great first impression and definitely worth using the sizing kit before ordering the actual ring!
