About this item

• 【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.
