Smart ring

It's built with aerospace-grade aluminum alloy and weighs only 2.5 grams. Once you put it on, you barely notice it's there. Many customers tell us it doesn't interfere with sleeping, typing, or exercising at all. Despite being incredibly light, it doesn't compromise on features: German Dialog chip, IP68/5ATM waterproofing, heart rate, blood oxygen, and sleep tracking are all included. If you're looking for a health device that users can 'put on and forget', the R14 is your best choice.
