"Oura has been busy developing a smart ring that's smarter and stronger than the rest, recently unveiling a device that surpasses the competition by a mile."
"The Ring 4 uses receded smart sensors to keep the inside flat and easy to wear, creating the most comfortable and unnoticeable generation of the device yet."
"Despite the added comfort, the absence of protruded sensor domes made the Ring 4 slippery, resulting in it falling off my finger while I slept."
"A major selling point of the Oura Ring 4 is its extended battery life of eight days, making it a standout compared to competing smart rings."
