Product Details

Thank you for looking.
This is a smart ring purchased on Amazon in September 2025. I am selling it because I bought a new smartwatch. It has a review rating of 4.1 stars! (^^) I always wore it, and it automatically measured my sleep and nighttime pressure, but there is some error compared to a regular pressure monitor as it only measures with a finger. For sleep tracking, the sleep and wake times seemed relatively close. The size is a US size 7. Many reviews said the sizing ran large, so I purchased one size smaller, and it fit perfectly on my index or middle finger (I've included a photo showing how to measure your size).
There are minor scratches, but no noticeable damage.
Please note that returns are not accepted.

As this is a used item, please refrain from purchasing if you are looking for a perfect product.

Size: 7 (US Size)

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.

Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.

Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.

Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
