COLMI R10 Smart Ring — Sleep & Health Tracking, 5ATM, Sizes 7–13
$50.00 CAD
Everything a fitness band does, on your finger, with no screen to distract you. Tracks sleep, heart rate and activity, and comes with its own charging case so it recharges away from a cable.
What you get
- Sleep and health monitoring — sleep stages, heart rate, blood oxygen.
- Multi-sport modes — logs different activities rather than counting everything as steps.
- 5ATM water resistant — genuinely swim-safe, unlike most watches in this shop.
- Charging case included. Gold, silver or black, sizes 7 to 13.
Worth knowing before you buy
Sizing is the thing people get wrong. Ring sizes here are US sizes, fingers swell during the day and in heat, and a ring that spins will not read your pulse properly. If you are between sizes, measure in the evening and size up.
This is a wellness device, not a medical one. Useful for spotting trends in your own sleep and resting heart rate; not a diagnostic tool.
