About This

【Find Your Perfect Fit】Before purchasing your Benio Smart Ring, we strongly recommend using our sizing kit to find your most accurate and comfortable fit. Note: This kit is designed specifically for Benio Smart Rings.
【Full Size Range】Both the sizing kit and the ring are available in a wide range of sizes to fit most fingers.
【24-Hour Fit Test】For the best result, place the sizing ring firmly at the base of your chosen finger—it should not spin freely. Wear it for a full day to confirm comfort.
【Best Fingers for Wear】For optimal sensor accuracy and comfort, we recommend wearing your ring on your index, middle, or ring finger. Please measure the exact finger you plan to use.
