A Verge shopping article by Brad Bourque reports the previous-generation Oura Ring 4 on sale for as low as $249 at Amazon, Best Buy, and Target, $100 off, and judges it almost as good as the newer Oura Ring 5, which is lighter and thinner but has the same sensors and software. He notes it is the first big discount since July, while full features require a $5.99 monthly or $69.99 yearly subscription.
