Ultrahuman Ring Air-Size08-AsterAirBlack

Smart Ring sizes are unique, and different from standard UK ring sizes. We strongly recommend that before you buy an Ultrahuman Air Smart Ring, that you buy an Ultrahuman sizing kit so you can be sure that the size ring you choose will be comfortable and give you the best tracking information. You can find the kit using the search option or typing the 4076638 into the search bar. They're available to be ordered to collect from all Argos collection points at your convenience. The kit costs £10, but there will be a voucher in the box to claim the cost off the price of the ring when you buy it. Ultrahuman Ring AIR is the perfect sleep tracker ring. Along with insights on all your sleep stages - REM, Deep Sleep, Light Sleep and Wakefulness, get actionable steps to improve sleep so you're ready for the day. The 'Movement Index' is designed to keep you moving all day for optimum glucose metabolism, and to increase your non-exercise energy usage through the day. Meticulous
