Oura Ring is FSA/HSA Eligible — we can accept FSA or HSA funds for the following: Oura Ring, additional chargers, and shipping. Oura Ring 4 Ceramic Polishing Pad: Keep your Oura Ring 4 Ceramic looking like new with the Ceramic Polishing Pad, redeemable once you sync your purchase in the Oura App. Due to the hardness of the zirconia ceramic, it can take on the color of softer metals, like a dumbbell or cookware. Over time, you may notice grey marks on your Oura Ring 4 Ceramic. Rest assured, it's not damaged — it's evidence of a metal transfer and easy to remove with proper cleaning. Use caution when handling metal objects and consider removing your Oura Ring for some activities. The Oura Ring 4 Ceramic Polishing Pad is your partner in keeping your ring in top condition. IMPORTANT: Size yourself with the Oura Ring Sizing Kit before you buy — Oura Rings are not US standard sizing, and finding the right size will result in the best experience possible. With a sizing kit purchase, a credit will automatically be applied to your Oura Ring at checkout.

  • Wasn’t Sure at First—Now I’m So Glad I Have It
Style: Ceramic Color: Cloud Size: 8
I wasn’t sure I wanted the Oura Ring 4 Ceramic, but just 48 hours in, I’m so glad my husband got this for me for Christmas. It’s already become something I check daily. Comfort & Design: The ring is incredibly comfortable and lightweight. I honestly forget I’m wearing it, even while sleeping. The ceramic finish looks sleek and modern and feels very high-end. Insightful Tracking: The data is fascinating and easy to understand. Sleep, readiness, and activity insights feel meaningful and helpful—not overwhelming. It’s already made me more aware of my sleep quality and recovery. Easy to Wear, Easy to Use: I love that it doesn’t feel bulky like a watch and works seamlessly in the background. The app is intuitive and well designed. Quick Buy-In: I expected this to be something I’d have to “get used to,” but instead I was hooked almost immediately. Within two days, I understood the value. Overall Impression: If you’re on the fence like I was, this might surprise you. Comfortable, insightful, and beautifully designed—it’s a gift I didn’t know I needed but now wouldn’t want to be without. ... show more

  • Smart, Sleek, and Surprisingly Insightful!
Style: Ceramic Color: Cloud Size: 9
I absolutely love my Oura Ring 4! It’s lightweight, stylish, and so comfortable that I forget I’m even wearing it. The sleep tracking is incredibly accurate and has helped me improve my bedtime routine. I also appreciate the readiness and activity scores — they make it easy to understand how my body is doing day to day. The battery life is impressive, lasting several days on a single charge, and the app is very user-friendly with clear insights and tips. I also love that it looks like a simple, elegant ring rather than a bulky fitness tracker. If you’re serious about improving your health, sleep, and daily performance, the Oura Ring 4 is worth every penny. It’s like having a personal wellness coach on your finger! ... show more

  • 🔥
Style: Ceramic Color: Cloud Size: 11
I had a couple of watches with trackers, but the ring is something!!!! I’m so glad I bought it. It’s super light — I barely feel it on my finger, yet it tracks everything — sleep, readiness, heart rate, body temperature, even stress levels. The insights are so much more accurate than any smartwatch I’ve tried before. I love checking my sleep score in the morning — it actually helps me understand how my body feels that day. And the design? Minimal, elegant, and goes with literally any outfit. Totally worth it if you care about your health and want something that doesn’t scream “fitness tracker.” ... show more
