Oura Ring 5 review: best smart ring Oura has made, but not a big upgrade from Ring 4

The Oura Ring 5 is the best smart ring Oura has ever produced, though it falls short of being the major upgrade Ring 4 owners have been anticipating. It delivers improved health and activity tracking features but does not introduce the step-change improvements long-time users were hoping for. Despite this, it retains its position as the top smart ring on the market.
