Oura Ring 5 review: Thinner, lighter, better
” My second thought was that this is a smart ring a lot of people have been waiting for.
As someone who got quite used to wearing the Oura Ring 4 Ceramic, I was surprised how noticeably smaller and lighter the new Ring 5 is.
The Ring 5, which Oura describes as the world’s smallest smart ring, is 40% smaller than its predecessor, measuring 6.09 mm wide compared to the Ring 4’s 7.90 mm, and 2.28 mm thick compared to the Ring 4’s 2.88 mm. Although the exact weight depends on your ring size, the Ring 5 weighs between 2 grams and 2.69 grams, while the Ring 4 weighs between 3.3 grams and 5.2 grams.
