Review: Amazing product & customer support service!!!! - I absolutely love this ring and all it offers. I’ve recommended it to everyone who has asked about it in the 11 months I’ve been wearing it (24/7). I know at least one person who has purchased one based off of my recommendation. Lately, within just the last few weeks, I’ve noticed the battery life has decreased sufficiently. Going from 5-6 days between charges to 2-3 days. Then the last week, I’ve begun having connectivity issues. While frustrating, I love this ring. So much so that I was seriously considering buying another one. But that $400.00 price tag is steep. Today I decided to submit a question for help through the app. Within 5 minutes tops, the virtual assistant determined I was indeed having issues, confirmed the ring I have is in stock and informed me that a replacement would be shipped with arrival time at 1-2 weeks. I am just under the year (purchased 4/8/2025 and today is 3/4/2026) but that was unexpected and honestly, amazing!!! I am so impressed. Enough so, I came to desertcart to write a review (which I never do). I will continue to recommend this product to anyone and everyone who asks!!!
Review: ⭐⭐⭐⭐⭐ 5/5 – Game-changer for my fitness and wellbeing - I work out 5 days a week, and my Oura Ring Gen 4 has been an absolute game-changer for my routine and recovery. The sleep tracking alone has helped me understand how my body actually recovers, not just how hard I train. Seeing my sleep quality, readiness, and recovery metrics every morning has completely changed how I plan my workouts. What really stands out is how seamlessly it tracks my overall wellbeing—from sleep stages and recovery to daily readiness and trends over time. It’s helped me dial in better habits, know when to push hard, and when to prioritize rest. The insights feel meaningful and actionable, not just data for data’s sake. On top of that, it’s comfortable, unobtrusive, and easy to wear 24/7. The battery life is great, it runs easily for about 6-7 days with one full charge, plus it charges pretty quickly. If you’re serious about training, recovery, and long-term health, this ring is 100% worth it. I honestly can’t imagine my routine without it now. 💪

### ⭐⭐⭐⭐⭐ Love it!
*by E***S on February 16, 2026*

I love this ring. I bought this for my husband since I already have one and he’s loving it so far too. It really helps see a picture of health markers that aren’t tracked as often. I tried knock off brands and although cheaper, you get what you pay for and they were unreliable and inaccurate. Oura is always on point and accurate. It’s worth the investment for me since health is so important to me. It broke my heart to watch my mother succumb to illnesses and disease that could have been prevented if she had just taken the steps to monitor sooner. This is a tool we use in addition to diet and lifestyle. I highly recommend.
