What to know before buying

Battery claims are listing estimates: up to 3-5 days for the ring after a 2 hrs charge, and about 15 ring charges from the 400 mah case. The stated 60 days is an extended-use claim, not a single ring charge.
The title specifies gold, size 6#. Follow the listing's size chart and sizing guidance before ordering, since fit affects whether the ring stays on comfortably.

Listing details to confirm

The listing is inconsistent about water protection. It claims IP68 and Waterproof, and separately lists 100 meters, but does not explain how those claims relate. It also lists Android Wear 2.9 despite presenting the product as an Android and iOS phone-connected ring. The warranty fields conflict between 2 years warranty and Lifetime. Confirm the applicable protection, software and warranty terms before purchase.

Customer feedback highlights the ring's appearance and comfort, and reports favorable experiences with sleep and heart-rate tracking, functionality and battery life. That aligns with its listed screen-free tracking and charging case, though reported impressions do not verify measurement accuracy or the battery estimates. Ratings are mostly five-star, with a smaller spread of lower ratings, so experiences are not uniformly positive.
