FKGZJF Smart Ring lovar heltäckande sömnspårning, puls, blodsyre och HRV utan månadskostnad – allt i en diskret ring i titan. Vi har testat den i tre veckor. Här är vad du faktiskt kan förvänta dig.
The BIEMHA Smart Ring promises waterproof design, sleep monitoring and no subscription fees. After two weeks of daily wear I can tell you exactly where it delivers and where it falls short of the hype.
The TYUIOL Smart Ring promises sleep tracking, heart rate monitoring, and step counting in a waterproof titanium-free shell — all without a monthly fee. After wearing it for three weeks across workouts, commutes, and a few rough nights, I have some thoughts on whether this budget ring can actually keep up with the sleep-focused features that matter most on SleepBetter.
