Smart ring

only 2.4mm thick and weighing around 4g. Once you put it on, you barely feel it's there. Many customers tell us it doesn't interfere with sleeping, typing, or exercising at all. Plus, we use the German Dialog chip for ultra-low power consumption — one charge lasts 7-10 days. If you're looking for a health tracker that can truly be worn 24/7, the R12 is your best choice. We'd be happy to send you a sample to experience it firsthand.
