R9 Smart Ring - Health Monitoring, Gesture Control, Somatosensory Games (Black)
Meet the R9 Smart Ring – not just a piece of jewelry, but your 24/7 health guru. It's sleek, it's light, and it's got more tricks up its sleeve than a magician. Keep tabs on your heart rate, blood pressure, blood oxygen levels, and even how well you're sleeping (or not sleeping, let's be honest).
Ever wished you could control your videos with a wave of your hand? Well, now you can. With Gesture Control, flipping through your favorite content is as easy as flicking a crumb off your shirt.
Battery life? It's a beast. Lasting 5-7 days on a single charge and juicing up in just 30 minutes, it's like the ring version of a caffeinated squirrel – always ready to go.
Rain or shine, sweat or splash, the IP68 Waterproof rating means this ring doesn't shy away from a little water. Go ahead, wear it in the shower (though we can't promise it'll help you hit those high notes).
Compatible with Android 6.0 or above and iOS 11.0 or above, the EcTri app turns all that data into something actually useful – like knowing if you're burning calories or just burning the midnight oil.
What's in the box?
- One smart ring (because wearing two would just be showing off)
- A charging cable (for when the squirrel runs out of coffee)
- User manual (for those who read instructions)
- Original retail box (perfect for storing your hopes and dreams)
