Unless you’ve been OOO for the past 24 hours with your phone on DND mode, you’re probably aware that it’s Prime Day. And you likely know that this year the event is four days instead of two. The sheer volume of sales is enough to make your head spin, and the extended time window probably has you wondering if the deals are changing each day.

Ring kits make it easy and affordable to get real home security at a price that makes sense.

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.
