Hidden in an elegant stainless-steel body, you’ll find not only a sophisticated heart-rate sensor, but also sleep, blood oxygen, and physical activity tracking.

TIP15-day delivery via Aliexpress Standard Shipping

For this product, Aliexpress Standard Shipping is available with guaranteed delivery within 15 days. It’s the most reliable delivery method and, in most cases, it’s handled by a courier company. The 15-day delivery is something we actually tested.

When you order from a Chinese warehouse, AliExpress adds a customs duty charge of approximately 3,70 € per order to your cart. When you receive the shipment, you won’t have to pay anything extra.

Are you shopping on AliExpress for the first time?

The process is via the AliExpress mobile app, where most people shop. There are two key things: don’t use Buy now and enter the coupon only in the order summary, in the field Promo code. After you click Pay now, you won’t be able to add it.

1. Copy the code and click Use discountIn our article, copy the coupon and click the button GET DISCOUNT. The link will take you directly to the product in the AliExpress app.
2. Use Add to cart instead of Buy nowOn the product card, scroll down and tap Add to cart. Don’t use the Buy now button—you’ll skip the cart, and later you won’t have anywhere to enter the coupon. Before that, double-check the variant: the color, the version, and whether it ships from an EU warehouse.
3. Through the cart, go to CheckoutA pop-up will appear: Added to cart! — tap Check it out in it. If it disappeared, open the cart with the icon at the bottom right. In the cart, check the product and quantity, then click the red Checkout. Only the items marked with the red ring will be applied.
4. Enter your address and card, then look for Promo codeIn the order summary, first fill in the delivery address and payment card at the top. Below them there’s a line Promo code — expand it with the arrow on the right.

   

5. Paste the code and confirm ApplyIn the field Promo code paste the copied code and click the black Apply. The code is case-sensitive and must not contain spaces.

   

6. Check the savings and payIn the Summary expand the line Saved — you’ll see the applied coupon there as AliExpress coupons/codes. Only when Total is really lower, click Pay now.

   

Apply the discount already at the order summary. After you click Pay now, you can no longer add a coupon. If Apply shows an error, the code has either expired, doesn’t apply to your items, or the order doesn’t meet the minimum amount.

The Store Coupon also goes in the same field. — a coupon from the seller itself, which isn’t always available and changes from day to day. AliExpress coupons can’t be combined, so try both and go with the one that gives you more. Coins are added automatically.

Review6.0/10We tested[REVIEW] Colmi R10: An extremely cheap smart ring with style. But is it capable of reliable measurements?6.0/10Our overall editorial ratingRead review

How to choose the right size?

For the most accurate measurements, we recommend wearing the COLMI R10 smart ring on your index finger. If you prefer other fingers, a middle finger or ring finger also works. Avoid wearing it on a finger that’s narrower around the joint area—such rings may cause inaccurate readings or a loose fit.

Before buying, measure your finger circumference carefully. Use a thinner piece of string or a paper strip that wraps firmly around your finger—not too tight. Measuring tools that are too wide may lead to an incorrect size. Measure based on the part of the finger where the ring will normally sit.

Health and sleep monitoring 24/7

The COLMI R10 ring comes with a precise heart-rate sensor VC30F that works continuously and gives you an overview of your body not only during workouts, but also throughout your everyday day. It also includes blood oxygen saturation monitoring (SpO2), which is especially important during physical exertion or while you sleep. The ring automatically tracks your sleep cycles and shows you a detailed report right in the QRing app.

Sleep tracking is further divided into individual phases, so you can optimize your habits to improve recovery. Thanks to the combination of these features, you get your own health assistant right on your ring.

A design that suits everyone

The body of the COLMI R10 smart ring is made of high-quality stainless steel, which is not only corrosion-resistant, but also beautifully finished. You can choose from color options: black, silver, and rose-gold, so it fits your style. Available in standard sizes from 7 to 13, and thanks to its lightweight construction you’ll hardly notice you’re wearing it.

The smart ring is also water-resistant according to IP68 and 5ATM, so you can shower or swim with it without any worries. Battery life is another strong advantage—one charge lasts for several days, and with the included charging case you can recharge it up to 13 times, which means up to 39 days of use!

Bluetooth connectivity and a smart app

COLMI R10 uses energy-saving Bluetooth 5.0 BLE technology, ensuring a stable and low-power connection to your smartphone. The smart ring is compatible with devices running Android 5.1 and newer, as well as iOS 8.0 and higher. You can view all your data in the QRing app, which also supports Slovak and provides clear statistics on your health and activity.

The QRing app offers broad language support and provides clear charts, notifications, and reminders—making it a great tool for improving your lifestyle every day. It even supports different sports activity modes, turning the ring into a complete fitness accessory.
