One ring to rule them all? Hardly. Even though the Oura Ring 5 shot to the top of our smart ring recommendations when it arrived earlier this year, I wouldn't recommend you buy it in the Amazon Prime Day, or Big Deal Days, sales. Why? Because it doesn't have any discounts in the US or UK, making it tough to recommend.
Other smart rings on Amazon, although perhaps not quite as technically brilliant, offer better value for money overall than the Oura Ring 5 at full price. I've found a pair of deals — one in the US, one in the UK — that are worth consideration over the Oura Ring 5.

In the US, the RingConn Gen 2 Air is available for $159.20 (was $199) at Amazon. The RingConn Gen 2 Air is a smart ring with no subscription to speak of (making it even better value compared to the Oura) which was still good enough to be called 'the perfect entry-level smart ring' in our review, netting four stars. It does most of what you want without some of the Oura's smarts, but at less than half the price.
In the UK, we're seeing huge discounts on the Oura Ring 4, with the Oura Ring 4 Black and Silver models discounted to just £199 (was £349) at Amazon. That's a huge 43% off and although it's last year's model, it was good enough to get 4.5 stars in our review and be named our health and fitness device of the year in 2025.
