TOMTOP JMS Smart Ring with Blue Pedometer: IP68 waterproof
Here's the lowdown on what makes it tick: First off, it's got a step counter because knowing how many steps you've taken is half the battle (the other half is actually taking them). Then there's the 18 mAh battery that laughs in the face of charging cables, offering up to 7 days of standby time. And let's not forget the fit—snug as a bug with an inner diameter of 20.7mm / 0.81in.
Whether you're crushing it at the gym or just crushing the couch, this smart ring is all about keeping pace with your life—no judgment here.
