Which smart ring detects illness the best? During a week with the flu, I tracked how different rings (Oura, RingConn, Ultrahuman…) and other wearables (Whoop, Garmin Fenix 8, Apple Watch Ultra, Elonga) responded. Which devices gave an early warning — and which ones failed?

Let me share a strange experience. Maybe you've heard rumors about defects and poor customer service from Circular. Well, I faced a critical issue—Error ES02: Upload Error. Luckily, I had a second Circular Slim for testing. Then things got even stranger!

The holidays of capitalism 🎉, Black Friday and its counterparts (Cyber Monday, Christmas?), are here! And if I put aside the often overwhelming aftertaste of consumerist marketing, I have to admit it's a chance to save some money. Maybe even on a new smart ring.
