But what makes the Oura Ring Gen 4 stand out among its competitors? Well, what doesn't? To start with, it is the most customizable smart ring on the market, and by a long mile — it is available in 12 sizes and nine colors, whereas most other models offer a maximum of three options here. The Oura Ring Gen 4 can suit almost everyone, whether you are looking for an unobtrusive black wearable or a glitzy gold jewellery piece.
More importantly, it easily outperforms other smart rings when it comes to tracking accuracy, battery life and durability. Not only does it offer some of the best sleep metrics of all the wearables we tested, but it has an unusually high resistance to scratches, AND it lasts up to eight days on a single charge. True, the Oura Ring Gen 4 requires a monthly subscription, and it can feel quite bulky at times, but trust us when we say it is worth it. If sleep and stress management are at the top of your priority list, you will be hard-pressed to find a better fitness tracker. Now, you can snap it up for under $250. But hurry, this deal will not last long.

Reviews consensus: Universally rated as one of the best smart rings ever made, the Oura Ring Gen 4 is highly regarded for its exceptional customizability, long battery life, good tracking accuracy and user-friendly, feature-packed app. Many reviewers also appreciate its stylish looks and relatively durable build, with some noting that it felt much more comfortable to wear than the older Gen 3 model. The negative remarks, though few and far between, revolved mostly around its high upfront price and the ongoing subscription costs.
