• ‘ZDNET Recommends’: What exactly does it mean? • ZDNET’s recommendations are based on many hours of testing, research, and comparison shopping. • We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites. • And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing. • When you click through from our site to a retailer and buy a product or service, we may earn affiliate commissions. • This helps support our work, but does not affect what we cover or how, and it does not affect the price you pay.
Article Summaries:
- ZDNET reviewed the Oura Ring 3 and its successor, the Oura Ring 4, after two years of testing. The newer model offers an eight‑day battery life versus the Ring 3’s seven days, and both charge in 20-80 minutes. The Ring 4’s fully titanium build and expanded sensor array (18 pathways versus 8) deliver more accurate data and a flatter interior, reducing finger dents that users reported with the Ring 3. Design options remain similar, but the Ring 4 starts at $350 compared to the Ring 3’s $300. ZDNET recommends the Ring 4 for users prioritizing comfort and sensor accuracy, while the Ring 3 remains a cost‑effective choice.
