Amazon is hosting its annual Prime Day event, but for 2025, it is 4 days long (rather than 2). We're rounding up all of the best deals of the event so far and updating this article live with the cream of the crop.

Smartwatches aren’t for everyone. Maybe you don’t want to wear a screen-equipped gadget to bed, or you’re just after something that’s less obtrusive. Subtlety is where smart rings like the Oura Ring 4 shine, and Prime Day has knocked down its cost. It costs $296.65 ($52.35) from Amazon, which is both its best price and first significant discount.

For the first time ever, Oura Ring is marking down its latest iteration, the Oura Ring 4, for Prime Day. Men’s Health is sharing it so you can get a leg up on purchasing the ring at a discounted price. Oura Ring is keeping sale details on lock but anything off £500 is worth checking out.
