Oura Ring 4 review: $399 health tracker or expensive jewelry?
The Oura Ring 4 is a sleek, comfortable health tracker that genuinely excels at sleep and cycle monitoring, especially for people who hate smartwatch screens. The catch: you're paying $399 upfront plus a $5.99/month subscription for insights that sometimes feel like expensive confirmation of what you already suspected. Battery lasts 5-8 days (solid), but durability complaints suggest you might replace it annually, which stings at this price.
