TOMTOP JMS Smart Ring: Tracks movement up to 50 meters
Meet the Smart Ring—your new workout buddy that doesn’t just sit there looking pretty (though it does that too). This little marvel tracks your every move with scary accuracy, up to 50 meters, so you can’t even sneak a cookie without it knowing. Made from lightweight aluminum alloy, it’s tough enough to handle your most intense sessions but light enough you’ll forget it’s there. And yes, it’s waterproof, because sweat and rain shouldn’t stop you (or your ring). Plus, that sporty design? It’s like the cherry on top of your fitness sundae.
Why you’ll love it:
- Keeps up with your long-range adventures (or just your coffee runs)
- Laughs in the face of rain, sweat, and the occasional splash
- Built to last, without weighing you down
- Looks so good, you’ll want to wear it even on cheat days
