Top complaints
Ultrahuman Ring Pro
- 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.
RingConn Gen 2
- Battery stops holding a charge; rings stop working
Amazon's review summary says some owners report the battery stops holding a charge and the ring stops working after a few months, and calls durability a concern.
- Few workout modes
Tom's Guide notes it tracks a relatively modest number of activities, such as running, cycling and yoga.
- Mostly a secondary recommendation
WIRED lists it as an honorable mention, mainly $100 more than the Gen 2 Air for sleep apnea monitoring, VO2 max and titanium. Amazon owners are split on whether it's worth the price.
