The Oura Ring 4 is our choice as the best smart ring, and its Brushed Silver variant is on sale for the first time during Amazon's Prime Day at 15% off.

In honor of Prime Day, Amazon is going against the norm with the first-ever price cut on Oura Ring 4: With a 15% reduction on all sizes, you can now buy the Oura Ring 4 in silver, size 10, for $297 from $349. Other sizes are also on sale, but some of them are already sold out.

With the Oura Ring 4 only launching last October, we weren’t expecting a discount anytime soon—so this Prime Day deal comes as a very welcome surprise. For the first time ever, Oura’s latest smart ring is 15% off exclusively on Amazon, making now the perfect time to invest in the cult-favourite health tracker.
