This Amazon deal marks the first-ever discount on the new generation of the stylish, celebrity-loved smart ring.

You can then talk to whoever is at the door, which means that weird delivery instructions can be cleared up, or that last-minute trips out don’t have to be massively disruptive. The motion detect means that you’ll get notifications to your phone whenever there’s relevant movement.

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.

Expect big discounts on Hollywood-loved sunscreens, Sony headphones, Dyson vacuums and hair tools, Unwell Hydration and other bestselling products.
