Description

If you encounter problems, how should you deal with them? You can read the manual carefully, watch the demonstration video, or communicate through the in-site message. How do you determine your size? We suggest you purchase the size kit. Once you buy it, both your family and friends can use it. Of course, it can also be measured according to the method provided by the scale. Please wear it for an extra day! It takes some time for the ring to fit your finger to obtain accurate data. We suggest wearing it for at least two days Comparison of data accuracy The Kuxlagz smart ring combines your step count with your step length (based on height data algorithm), which is real consumption rather than based on GPS. The algorithm of lying still and heart rate truly reflects your sleep.

  • Completely Replaced My Galaxy Watch 6—Best Switch I Ever Made!
Color: Enamel Color Size: #10
I never thought I would ditch my Samsung Galaxy Watch 6, but this Kuxlagz Smart Ring has completely blown me away. In every single aspect—physical comfort, technical performance, aesthetic look, build quality, and tracking accuracy—this ring outperforms my old smartwatch by miles.Physically, the change is liberating. At just 3 grams, it feels incredibly ultra-light. I used to hate the bulk of a smartwatch on my wrist, especially when trying to sleep or working out. This ring is so comfortable that I completely forget I am wearing it. The titanium steel build quality feels premium, durable, and handles daily wear seamlessly. Visually, it is stunning. The unique, colorful enamel design elevates it from a mere tech gadget to a beautiful piece of jewelry that actually complements my style, unlike a clunky screen.Technically, it delivers everything I need without the annoying notifications or constant screen distractions. The health tracking accuracy has been phenomenal. I’ve closely monitored the heart rate, SpO2, and sleep tracking, and the data feels incredibly spot-on and reliable compared to my Galaxy Watch. Tracking my sleep is finally effortless, and the 5-day battery life is an absolute game-changer. I no longer suffer from daily battery anxiety or have to plan my schedule around charging a watch.The fact that it packs 5ATM waterproofing means I can wash my hands, shower, or swim without a second thought. Best of all, there are absolutely no hidden subscription fees to access my health insights. It syncs beautifully with my phone, offering a streamlined, mindful approach to wellness. If you are on the fence about moving from a smartwatch to a smart ring, do it. This is a massive upgrade in lifestyle, style, and comfort! ... show more

  • Cute and functional
Color: Enamel Color Size: #7
I wanted to try a smart ring without spending money on a big brand and this one is very nice! I ordered my ring size and it fits as expected. I don’t normally wear thicker rings but this one is comfortable to wear and doesn’t feel too bulky. I forget I have it on half the time! The instructions are clear on how to wear it and connect it to the app. It tracks my vital signs and even gives a pretty accurate blood pressure reading which was surprising! The battery lasts for several days, I think 5-6 days. It tracks my sleep in great detail, I only wish that I could figure out how to program it to track my sleep during the day as I work night shift. It doesn’t seem to pick up any sleep during the day and just tells me that I’m not sleeping enough, which is probably true. Cute little ring. Highly recommend! ... show more

  • Does as expected! Scratches easily.
Color: Gold Size: #9
The ring does what I wanted it to do which was track my sleep since I don’t like wearing my Apple Watch to bed. It has monitored blood pressure, steps and everything else very accurately when compared to my watch data I will say that it was beautiful when I first got it and it does scratch so it’s going to look worn fairly quickly. I’ve been wearing it daily for less than a week and it has some obvious signs of scratching, even though I haven’t done anything major with it other than that. I do love it. It’s great for the purpose! ... show more

  • A very useful smart ring . I love it 😍
Color: Enamel Color Size: #7
I've been using this smart ring for 10 days now. It's lightweight and comfortable, and you barely feel it when wearing it. The app is easy to use, and I love that I can check my sleep, heart rate, and daily activity on my phone. I'm very pleased with this elegant and beautiful smart ring. It's definitely a great option if you're looking for a discreet device to track your health and daily activities. I highly recommend it! ... show more

  • Terrible product
Color: Gold Size: #13
The inner ring material made my skin breakout. Took one week to cure. Terrible “gold” exterior. Really stands out in a negative way compared to my wedding ring. The software is clumsy. Look elsewhere

  • Stylish and Works Great!
Color: Enamel Color Size: #10
I’m very happy with this smart ring. It works well, is comfortable to wear all day, and the health tracking features are easy to use. The battery lasts a long time, and it looks great too. For the price, it offers excellent value and has exceeded my expectations.
