If there’s one piece of tech our editors won’t shut up about, it’s the Oura Ring. Not only does this wearable offer tons of health tracking metrics like heart rate, steps, and cycle tracking, but it also blends seamlessly with your everyday jewelry stack. As someone who’s finally ready to make the switch from my trusty Apple Watch to this chic piece of tech, dare I say I manifested the Oura Ring 4 dropping down to its lowest price ever for Prime Day?

Depending on the finish you choose, you can snag one of these wearables for as little as $215. Earlier this week, I predicted that this record-low deal would be one of the first to sell out during Prime Day, and now that we’re in the final hours of the sale, a handful of colors and sizes are already out of stock. (Prime Day ends tonight, Friday, June 26, so don’t forget to finalize your cart and check out ASAP!)

With the recent release of the Oura Ring 5 a few weeks ago, I assumed the previous generation would be discounted, but scoring one for so cheap is truly unheard of. I’m not exaggerating when I say you should rush to shop; several Oura Ring sizes and finishes went in and out of stock in the middle of updating this story.

Wondering what all of the fuss is about? Not only does the Oura Ring track over 30 biometrics—think sleep, activity, stress, recovery, heart health, cycle tracking, and temperature—but it looks straight-up chic when paired with your jewelry. It’s also super easy to use with the handy Oura app. Every morning, you’ll get a detailed look at your overall health for the day, so you can accurately prioritize activity, rest, and stress without overdoing it. Plus, it’s great at logging step count, caloric expenditure, and workout stats, helping you stay locked in on your fitness goals.

Contributor Hannah Oh went so far as to say that it completely fixed her sleep (I fear I’m about to become obsessed with checking my sleep score every morning), while senior shopping editor Samantha Jones said it was an integral tool in helping her prioritize recovery days during multiple marathon training cycles.

I can’t emphasize enough how rare this deal is. Last Prime Day, these were only 15% off, so this is truly an unprecedented discount. With stock constantly fluctuating, if you want to save big, there’s no time to waste.
