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.

Review: Great health and fitness tracker. - I got this in a black Friday sale and I love it. I've had this now for 3 months and it has given me lots of insights and information on my habits, work outs and sleep patterns. It's a great investment when trying to monitor and work on your wellness. Using the sizer to get the right size worked perfectly for me. I don't even notice it when sleeping. I charge it when showering, so I don't ever really have to worry about it running out of power. I have the silver one and have actually gotten compliments on how it looks
Review: A great health tracker - I highly recommend getting an Oura Ring if you like keeping track of your health and I don't say it lightly. I am a Samsung girly and while I love all my Samsung stuff, I am disappointed with their Ring version. I went through 2 Samsung Rings before getting the Oura. Both Samsung rings had charging issues and stopped holding a charge. Now I have only had my Oura ring for almost a week, but I can already see that it tracks way better. The only thing I wish it could connect to is my Libre app for my Freestyle Libre 3 CGM. It does connect to Stelo by dexcom for those CGM users. I just hope that it could someday connect with Libre. Overall I am much happier.

### ⭐⭐⭐⭐⭐ Great for wellness and insight!!
*by K***S on July 17, 2025*

The ring fits on my right pointer finger just fine. That finger, for whatever reason, is wider than my left finger but it still fits well. After sleeping through the night, it’s a bit more snug. The information the Öura Ring provides through the app is helpful as I’m an extremely light sleeper. It has helped me understand my sleeping patterns and has predicted my cycle perfectly twice now. It records exercise/activity better than my Gen 8 Apple Watch but I’m not really comparing the two too much. It does have some light scratches but that’s to be expected when wearing it all day. The battery is at 88% after a full days use and I typically charge it in the shower. I would recommend this to someone who is looking for health and wellness details for themselves as the Ring really does provide great detail.
