COLMI R09 Smart Ring with Portable Charging Case
- 24/7 Advanced Health Metrics: Monitor your heart rate, blood oxygen levels (SpO2), body temperature, and stress levels continuously throughout the day and night.
- Intelligent Sleep Tracking: Gain a deeper understanding of your rest with detailed analysis of your sleep stages, quality, and recovery metrics.
- Feather-Light & Durable Design: Weighing just 3.5g, the ultra-lightweight titanium steel body offers maximum durability with a comfortable, unnoticeable fit.
- 5ATM & IP68 Waterproof Rating: Engineered to withstand depths of up to 50 metres, making it perfectly safe for swimming, showering, and intense workouts.
- Smart Activity Tracking: Automatically track your daily steps, distance covered, and calories burned to help you hit your fitness goals.

- Step 1: Wrap it – Take a strip of paper or a piece of non-elastic string, and wrap it comfortably around the base of your chosen finger.
- Step 2: Adjust the fit – Ensure the paper or string fits closely and snugly around your finger. Avoid pulling it too tight or leaving it too loose, as this will cause an inaccurate reading.
- Step 3: Mark the point – Use a pen or pencil to clearly mark the exact point where the paper or string overlaps and meets.
- Step 4: Measure the length – Lay the paper or string flat against a ruler and measure the distance in millimetres (mm). This measurement gives you your finger circumference. For the most accurate result, we highly recommend measuring 2 to 3 times.
- Remove any protective film from the ring's charging port before your first use.
- Place the ring into the included charging case or connect the charging cable. The heart rate sensor light will illuminate to indicate the ring has successfully powered on.
- Download the "Qring" app on your smartphone and follow the on-screen instructions to connect your device via Bluetooth.

Absolutely brilliant service! I was a bit sceptical at first, but my order arrived in the UK much faster than expected. The packaging was neat, and the item quality is top-notch. Customer support was incredibly helpful when I asked for a tracking update too. Will definitely be buying from this store again!
