## Description

RingConn Gen 2 Air Sizing Kit

Review: A must buy, to get the size for this brand - More expensive than other makes, but it does make a difference, so glad I bought these and didn't go by another make that someone let me borrow I would have been a size to small! I kept it on for the 24 hours, and when the ring came it was just the same
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 PURCHASE Before purchasing the RingConn Smart Ring, we strongly recommend buying the RingConn size set to determine the most comfortable and suitable size for your finger. Please note that the RingConn size set is only compatible with the RingConn smart ring.
- No standard size: The RingConn Smart Ring is different from other rings because it contains sensors inside. We therefore recommend using the RingConn size set to determine the best fit. The RingConn smart ring is available in sizes 6 to 14 to adapt to different finger sizes.
- Measuring and checking the fit: Place the gauge comfortably and easily around the base of your finger and make sure it does not rotate freely. We recommend using it for more than 24 hours to determine your setting as accurately as possible. For optimal data and comfort, the RingConn Smart Ring should lie perfectly on your skin without turning. When testing the appropriate size, make sure that the meter sits firmly on the finger.
- Choose a finger: The RingConn smart ring can be worn on any finger or hand. For optimal precision and comfort, we recommend wearing the RingConn Smart Ring on your index finger, middle finger or ring finger. For the optimal fit, ensure that the finger you wish to wear your RingConn Smart-Ring on is measured precisely.
- High Quality Construction: The RingConn sizing set is made from high-quality plastic, while the RingConn Smart Ring itself is made from titanium, which is used in the aerospace industry. In addition, it is coated with a scratch-resistant layer for excellent corrosion resistance and durability.
