If you've been Oura-curious but couldn't justify the price, this might be the deal that changes your mind. Both the Ring 4 and the Ring 4 Ceramic are nearly half off right now, making this one of the best opportunities I've seen to pick up a smart ring.

The Oura Ring is our favorite smart ring and, by extension, one of our favorite fitness and sleep trackers. It's comfortable, discreet, and most importantly, consistently accurate. It tracks activity, sleep, and key health metrics without demanding much attention from you.

Oura recently launched the Ring 5, which is about 40 percent smaller than the Ring 4. Having worn both, I can definitely notice the difference in size and weight. Oura also says the newer model is more accurate thanks to more powerful LEDs and redesigned sensors that sit closer to the skin.

That said, in my testing, I haven't seen a meaningful difference in the data. The Ring 5 is an impressive refinement, but the Ring 4 was already one of the most reliable wearables I've used, and its tracking remains excellent. Unless you're particularly excited about a lighter, slimmer design, this discount makes the older model a very compelling buy.

Plus, the Ceramic's pastel colorways are some of my favorite finishes Oura has made, and they're not available on the Ring 5 (yet).
