5 out of 5 stars

It works great!
This ring has worked perfectly for me. I love that it tracks my sleep hours and monitors my menstrual cycle, indicating when I'm ovulating. Plus, all the other health features it offers are incredibly helpful for my daily life.

    I’ve been using this smart ring for a week, and I’m really impressed! It accurately tracks my heart rate, sleep, and blood oxygen, and the app displays everything clearly. The battery life is surprisingly long, lasting several days per charge. It’s lightweight, comfortable to wear all day, and even works well during workouts or showers.

    A Great Gift for My Mom’s Health

    Reviewed in the United States on November 9, 2025

    Color: GoldSize: #7Verified Purchase

    I bought this smart ring for my mom, and she really loves it. She says it’s so light and comfortable that she forgets she’s even wearing it. The health tracking features are amazing, it shows her heart rate, sleep, and steps clearly on the app. She likes checking her daily data every morning. The battery lasts several days which is great for her since she always forgets to charge things. She also tried it while washing dishes and it’s still working fine, totally waterproof.

    Good smart ring for the price

    Reviewed in the United States on November 13, 2025

    Color: GoldSize: #8Verified Purchase

    I purchased this smart ring and so far the experience has been very positive. The design is sleek, lightweight, and comfortable; it feels like a regular ring but with integrated technology. The battery lasts several days without any issues and charges quickly.

    As for the features, the heart rate and blood oxygen monitoring work well for daily reference. I also liked the sleep tracking: it provides useful and easy-to-understand insights through the app. Syncing with my phone has been stable with no disconnections.

    It’s not as precise as high-end devices, but for the price it offers great value. It’s perfect if you want a discreet and practical wearable to keep track of your activity and daily wellness.

    Not worth it

    The only thing good about this item is the sleeping stuff. And I don’t think it’s accurate. Make sure to size up. You have to use an app to work this thing. Looks cute on.

    Essential and discreet.
    ​This ring is the perfect fusion of fashion and technology. It accurately monitors your heart rate, blood oxygen, and sleep without the need to wear a watch. It is waterproof and its elegant Gold finish makes it look like a piece of jewelry. The best invisible fitness tracker I have ever tried!

    Small ring, big help on monitor health!

    Color: GoldSize: #7Verified Purchase

    I specifically ordered this smart ring to help monitor my mom’s stress levels and heartbeat after discovering she has a heart condition with irregular rhythms. This little device has been very helpful—it continuously tracks her vitals and syncs the data to her phone, giving us real-time insights into her health. It’s reassuring to know that we can keep an eye on her heart activity so easily. The ring is discreet, comfortable, and surprisingly accurate. Highly recommended for anyone needing a reliable health monitoring tool for a loved one.

    Won’t hold a charge after 6 months

    Reviewed in the United States on November 8, 2025

    Verified Purchase

    Ordered this ring in May 2025. I am already having issues with it holding its charge. It barely lasts for one day. Additionally, not only is it not holding its charge, I’m having a very difficult time even getting it charged. I realize it was only $39 but I would’ve expected it to hold up better in a six month period. One thing I did like about the ring is how slim it is. I wanted to have a ring that I was able to wear and play golf in this worked perfectly.
