Top complaints
Oura Ring 5
- Membership on top of a $399 ring
PCMag and ZDNET list the price as a con, and WIRED says the $6-a-month membership 'still feels mandatory' because only the three daily scores show without it. Amazon's review summary says value for money is mixed, with some owners calling it overpriced.
- Workout tracking is hit or miss
PCMag calls automatic workout tracking hit-or-miss, CNET says it is 'not the best fitness tracker', and WIRED says it isn't the right choice for athletes who need live workout stats or built-in GPS.
- Sizing and reliability complaints
Tom's Guide notes the Ring 5 comes only in sizes 6-13 versus the Ring 4's 4-15. Amazon's summary says size is mixed, with some finding it smaller than expected, and functionality is mixed, with some saying it never works correctly. WIRED adds that Symptom Radar still isn't as predictive as Oura claims.
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.
