    Fits perfect, sizing is accurate. Program app and ring work great together, they sync fast.
    I set uo my ring to check my numbers every 30 minutes, but you can do longer time gaps. Fits comfortable and is waterproof. I went swimming for hours and rinf worked and works perfectly after being under water.
    Blood Pressure numbers are accurate they match the Doctors office.

    I bought this smart ring with some hesitation, since I usually prefer more traditional watches, but it turned out to be a wise purchase. The design is subtle and does not scream “gadget,” which makes it comfortable to wear even at formal gatherings. The small writing around the band, almost like something from Lord of the Rings, adds a mysterious and thoughtful touch, as if the device itself wants to whisper that health is a precious treasure. Battery life has been more than acceptable, lasting two days without worry, which is important for someone like me who forgets chargers. Sleep tracking is accurate enough to give me a picture of my rest, and it is interesting to see the difference on nights when I read before bed versus when I stay on the phone too long.

    This smart ring is awesome ! It’s lightweight, comfortable to wear, and tracks heart rate, sleep, and activity very accurately. I love that it’s waterproof, has up to 5 days of battery life. The app is easy to use with clear insights into daily health and sleep patterns. Stylish and practical, an excellent alternative to fitness trackers must buy!!

    The packaging was sleek and professional, and the sizing kit made it easy to find the perfect fit. The ring is lightweight, stylish, and comfortable enough to wear all day without even noticing it’s there. It connects quickly, works smoothly, and delivers accurate tracking as described. I love the modern design it doesn’t look bulky like other wearable devices, yet it provides powerful functionality. Definitely worth the purchase, and I highly recommend it for anyone looking for a discreet, reliable, and high-quality smart accessory!

    I am a HUGE LOTR fan and when I found this, let me tell you, I geeked out. Haha. I have an I watch and really wanted something that the battery life lasted longer and I could comfortably wear to sleep without being disturbed by a band around my wrist. This ring is made of really good quality steel, the inscriptions are identical to that of the real ring from the movies, and it charges very quickly! The app is user friendly and very easy to understand.
    The charging box it comes with is nice to have, in case I want to store it! When I put it to the test, it performed very well, in comparison! It is actually comfortable to wear to sleep too. I have been testing it for a week and the battery is still charged too. Connects easy to your phone and I have had no issues with Bluetooth breakage. I am so happy I paid right around 80 for this, the value is so worth it. Looks AMAZING. I’ve gotten a lot of compliments!

    I’m loving this smart ring! It’s so comfortable and lightweight that I barely notice I’m wearing it, even all day. It tracks my health stats accurately — steps, heart rate, and sleep and gives me helpful insights about my fitness and overall wellness. I especially appreciate how discreet it is compared to a smartwatch but still provides all the data I need. Perfect for anyone who wants to stay on top of their health without wearing something bulky on their wrist.

    Very practical and easy to use. The kit includes all the necessary measurements to accurately check ring sizes, both for women and men. The material is strong and lightweight, making it durable and comfortable to use when trying on sizes.
    It has helped me buy rings online without fear of making a mistake with the measurement.

    I purchased this ring on September 10, 2025, and so far I’m very happy with it. The design is stylish and looks like regular jewelry, but it has all the functions I need for health monitoring. It tracks sleep, heart rate, blood pressure, and oxygen levels quite accurately compared to other devices I’ve tried. I also like that it’s waterproof and the battery lasts several days before needing a recharge. The charging case is compact and easy to use, and syncing with the app on my phone was simple. I mainly use it for checking my sleep and daily activity, and the data has been helpful in adjusting my routine. The best part is that there’s no subscription fee — everything works right away.
