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.

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

  • It was my dream
I finally got my Oura Ring 4 — the ceramic edition — and it’s absolutely stunning. I’ve been wearing it for a week, and it tracks my sleep, recovery, heart rate, stress, and even menstrual cycles. The app gives clear insights and helps me understand what my body really needs. And before you order yours, make sure to get the sizing kit first — for the perfect fit. ... show more

  • Amazing health tech
The Oura Ring Gen4 is a stylish smart ring that’s great for tracking sleep and recovery. It’s comfy, lasts several days on a charge, and looks more like jewelry than tech. The only downsides are the price, required subscription, and limited fitness tracking compared to a smartwatch.

  • Oura Ring 4 Review – Great Data, Disappointing Durability
I want to start by saying that I truly value what the Oura Ring offers. The data, insights, and overall health tracking are excellent. Sleep, readiness, and recovery metrics are well presented and genuinely useful in daily life. From a functionality standpoint, this is a great device. Unfortunately, my experience with the ceramic ring material has been very disappointing. I loved the cloud color by the way. Less than three weeks into ownership, I accidentally dropped my ring while washing my hands, and it cracked cleanly in half when it hit the floor. For a device costing over $400, this level of fragility is surprising and concerning. This wasn’t a hard impact or extreme use — just a normal, real-life scenario that most people will experience. Because of this, I now have an expensive device that is no longer usable. While I did go ahead and order a replacement at my own cost (switching to the Stealth finish), I don’t see long-term value or durability in the ceramic versions. A wearable designed to be worn daily should be able to withstand minor drops without catastrophic failure. To be clear: ✔️ The data and insights are excellent ✔️ The concept and app experience are strong ❌ The ceramic ring material does not feel durable or worth the price I really want to love this product long-term, but the ceramic build quality makes it hard to recommend without hesitation. If Oura improves the durability of the ring materials, this would easily be a top-tier wearable. ... show more

  • Love the sleep tracking
The media could not be loaded. I love my Oura Ring 4 in Cloud! I went with size 11 after using the sizing kit, and it fits perfectly. The design looks sleek and feels super comfortable to wear all day. I especially like how it tracks my sleep and heart rate so accurately. Totally worth it!
