I have been wearing my Oura Ring for almost two years straight, and you'll see proof of that in every single Instagram photo and mirror selfie I've ever taken. And because it's such a permanent fixture on my right hand, naturally, I get asked a lot of questions about whether I like it, whether it's changed my health for the better, whether I think it's worth the purchase, etc. The short answer? Absolutely, yes. The longer answer? It's a little pricey, but it's worth the investment – especially if you can snag it during a sale moment like Amazon Prime Day.

And wouldn't you know it, it's your lucky day, because Prime Day is happening right now and runs through until Friday 11 July (i.e, tomorrow)! Prime members will be able to score up to 15% off the Oura Ring 4 via Amazon through the end of the sales event. This is the first time that this model (aka the newest one with the best battery life) has ever gone on sale – and you have one more day to nab the discount.
You'll be able to choose from the following colours: Rose Gold, Silver, Black, Stealth, Gold, and Brushed Silver. Each shade has a slightly different sale prices, even though the actual hardware of the ring is the same for each colourway. I personally went for gold to match the rest of my daily ring stacks, but a lot of my friends who I convinced to hop on the Oura ring train opted for the most affordable-yet-trendy silver colourway.
If you're unfamiliar with the Oura ring, think of it like a really chic, barely-there health monitor. It keeps track of your steps, your heart rate, your temperature, your cycle, your sleep, and lots of other biometrics that help you understand your body. And if you're concerned about purchasing the right size, don't worry – Oura has a workaround for you. If you purchase a sizing kit during Prime Day, you'll receive a £10 Amazon credit to use toward an Oura ring.
Take it from my roommates, coworkers, and friends who bought the Oura Ring at full price – now is the time to snag this discount before it ends on Friday!
