[Size before purchasing] Before you buy the RingConn Smart Ring, we strongly recommend you purchase the RingConn Sizing Kit to determine the most comfortable and suitable size for your finger.
[Not standard sizes] The RingConn Smart Ring is different from normal, standard-sized rings as it has sensors on the inside. Therefore, we recommend using the RingConn sizing kit to determine the most comfortable and suitable size. In addition, it is available in sizes from 6 to 14, allowing for different finger sizes.
[Manufacturing Quality] The RingConn sizing kit is made of high-quality plastic, while the RingConn Smart Ring is made of aviation-grade titanium and coated with a scratch-resistant layer, which ensures excellent corrosion resistance and durability.
[How to measure and pass control] Wear the size measurement tightly around the base of your finger and do not let it rotate freely. We recommend wearing it over 24 hours to determine the best fit accurately. For more accurate data and optimal well-being, the RingConn Smart Ring should fit snugly against the skin and do not turn. Therefore, make sure the ring stays close to the base of your finger when checking for the best size.
