R5 SIZE 8 Smart Ring - Health Monitoring & Multiple Sports Modes (Silver)
Ever wished you had a personal health guru on your finger? Meet the R5 SIZE 8 Smart Ring—your new wellness wingman. It’s not just about counting steps; this little powerhouse keeps tabs on your heart rate, blood oxygen levels, and even how well you’re sleeping (or not sleeping, let’s be honest).
Whether you’re a gym rat or just trying to remember where you left your sneakers, the R5’s got your back with sports modes for almost anything. And thanks to Bluetooth 5.1, it syncs with your phone faster than you can say "Where’s my data?" Dive into the EcTri app to geek out over your stats and see how far you’ve come.
Rain or shine, sweat or swim, the IP68 rating means this ring doesn’t bail on you. Plus, with magnetic charging, you’re juiced up in 30 minutes and good to go for a week. Talk about low maintenance.
Inside the box, you’ll find the smart ring itself, a charging cable (because cords are still a thing), a user manual (for those who read them), and the original retail box (for the collectors out there).
