Twievo R11 Fitness Tracker Ring: Heart rate monitoring
Here's the lowdown on what makes it cool: First off, it's got a 5ATM waterproof rating, meaning you can take it for a swim or a shower without a second thought. The design? So thin and comfy, you'll forget it's there—until it reminds you to move, that is. And get this: flick your wrist to snap photos or navigate your phone, because who has time for buttons? Plus, it plays nice with almost any smartphone out there.
What's in the box? Just the essentials: the ring itself, a charging case (because losing tiny things is a sport), two charging cables (one for home, one for... wherever), and a user manual (for those who read them).
