Only selling because I got the gold Gen 4 for my birthday. I love this ring. It does show signs of wear but they are only noticeable if you look close or zoom in with a camera. The Oura Ring Gen 3 Silver in size 7 is a stylish and durable activity tracker designed for both indoor and outdoor use. It features a 240 x 240 display resolution, electric cordless power source, and a battery life of up to 7 days. Made from titanium, this ring provides accurate measurements for heart rate and distance, as well as tracking sleep quality and water resistance. With a 1-year manufacturer warranty, this ring is compatible with iOS and Android operating systems, making it a versatile tool for unisex adults looking to improve their fitness and overall health.
