Description
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 blood pressure, but there is some error compared to a regular blood 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.
