## Description

RingConn Gen 2 Air Sizing Kit

Review: Accurate Fit, Comfortable All Day Wear Trial, Find Your Perfect Size - Simple, effective, and exactly what you need. It’s a sizing kit so there’s not much to overcomplicate but it does its job perfectly. I wore the sample ring for a full 24 hours, which gave me a really clear sense of the fit and overall comfort throughout the day and night. That trial period made a big difference, and I felt confident choosing my size. The fit ended up being incredibly accurate when I received my actual ring. Overall, the kit delivered exactly what it promised and made the whole process easy and reliable. Definitely a worthwhile step if you want to get the right fit the first time.

## Questions & Answers

**Q: What are the key differences between RingConn Gen 2 and Gen 2 Air?**
A: Gen 2 Air is made of titanium steel, offering a sleek, comfortable fit for everyday wear, while Gen 2 is made of titanium. Gen 2 Air covers key health tracking features, though it does not include sleep apnea monitoring.

**Q: Can I measure ring size without an official sizing kit?**
A: For the best fit, we recommend using our official sizing kit. Our smart ring uses exclusive sizing standards, different from regular rings and other brands’ smart rings. Use our dedicated tool for an accurate fit.

**Q: How do I ensure the best fit for my RingConn ring? / How to get the perfect fit size?**
A: Measure your non-dominant hand, with the kit’s protrusion facing your palm. Wear the sizing ring continuously for 24 hours (including sleep). Fingers swell in the afternoon/evening, so long-time wear helps you choose the most comfortable size.

**Q: How to judge if the ring size fits well?**
A: Fit should be snug but not painful. First Test: Fits closely with no gaps. Drop Test: Won’t slip off when your hand is down. Rotation Test: Twists gently with slight resistance.

**Q: How should I wear the ring correctly?**
A: The sensor inside the ring should be positioned on the palm side of your finger. Make sure the ring fits securely and comfortably at the base of your finger to ensure accurate data tracking.
