R08 SIZE 9 Smart Ring: Heart rate tracking
Meet the R08 SIZE 9 Smart Ring—your new health and fitness sidekick. Packed with a Realtek chipset and Bluetooth 5.2, it connects smoother than a fresh jar of peanut butter. And thanks to the ST LIS2DOCTR sensor chip, it’s like having a mini doctor on your finger, tracking everything from your heart rate to how well you’re sleeping (or not).
Whether you’re running, lifting, or just trying to remember where you left your keys, this ring’s got multiple sports modes to keep up. Plus, its 15mAh battery laughs in the face of daily charging, lasting 5-7 days on a single charge (and up to 15 if you’re just showing it off). Charging? A breeze with the magnetic method—no fumbling required.
Love water? This ring’s 5ATM waterproof rating means it’s ready to dive in with you, whether you’re swimming or just forgetting to take it off in the shower. Compatible with Android 5.1+ and iOS 8.0+, and with the QRing app speaking multiple languages, it’s practically a polyglot.
📦 What’s in the box: One smart ring (because wearing two would be overkill), a charging cable, a user manual (for those who read them), and the original retail box (for when you need to impress someone).
