## 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.

## Features

- [Size Before You Buy] Before purchasing the RingConn Smart Ring, we highly recommend acquiring the RingConn Sizing Kit to determine the most comfortable and suitable size for your finger. Please note that the RingConn Sizing Kit is only compatible with the RingConn Smart Ring
- [Not Standard Sizing] RingConn Smart Ring differs from standard rings as it contains sensors on the inside. Therefore, we recommend using the RingConn Sizing Kit to determine the best fit. The RingConn Smart Ring is available in sizes 6 to 14, accommodating various finger sizes
- [How to Measure & Fit Check] Wear the sizing gauge snugly around the base of your finger, ensuring it doesn’t rotate freely. We recommend wearing it for over 24 hours to determine your most accurate fit. For optimal data and comfort, the RingConn Smart Ring should fit snugly against your skin without rotating. When testing for the best size, make sure the sizing gauge remains tight around the base of your finger
- [Choose a Finger] The RingConn Smart Ring can be worn on any finger and on either hand. For optimal accuracy and comfort, we recommend wearing the RingConn Smart Ring on your index, middle, or ring finger. Be sure to size the exact finger on which you plan to wear your RingConn Smart Ring for the best fit
- [Manufacturing Quality] RingConn Sizing Kit is made from premium-grade plastic, while the RingConn Smart Ring is crafted from aerospace-grade titanium, coated with a scratch-resistant layer for outstanding corrosion resistance and durability
