not available
Ultrahuman's redesigned ring is sold in the US at $479 after the Ring Air was blocked over an Oura patent (CNET, Engadget). It offers 10+ days of battery and a feature-rich charging case. Engadget rates it 8.9/10, but ZDNET gives it 3/5, calling it chunky and more expensive than the Oura Ring 5.

Top complaints
- Chunky, with protruding sensors
ZDNET says it's thicker than the Ring Air and the 2.28 mm Oura Ring 5 (2.65 mm), with protruding sensors that made it less comfortable. Engadget says the all-titanium body feels chunkier.
- Expensive, with paid add-ons
Both reviews say it costs more than rivals ($479). Engadget notes extra features come as paid Power Plugs, including AFib detection for a monthly fee.
- Shipping delays and pushy coaching
ZDNET cites customer reports of shipping delays and found the app's coaching intrusive. Engadget found activity detection lacking at times.
What owners love

Engadget had 9% left after 10 days in Turbo Mode. The case stores 45 days of power and a year of data, and handles firmware updates (Engadget, ZDNET).
- Data-rich, improved app
Engadget praises the data-rich app; ZDNET says a recent update improved the interface and visuals.
- Designed for safety and US availability
Engadget says the ring can be cut open easily if the battery swells. CNET says the Ring Pro is available in the US.
