    I love my ring. Made very well. It does everything great. Tracks everything about your health, can even tell you when you're getting sick before you realize you are. I use it mainly for gym and sleep, but it does way more.

    I had gotten myself an oura ring and when my husband saw mine he wanted one for himself so we went and got him one and he is absolutely obsessed! I use it for cycle tracking but my husband loves seeing his sleep patterns and calorie burn. We will definitely keep buying Oura rings as they continue to perfect they’re technology.

    My oura ring is awesome. I didn’t get the ceramic because the colors don’t really “match” an everyday outfit for me. I’m a gold-lover. However, after watching countless reviews, the gold and rose gold fade poorly. I opted for silver, which is also beautiful. Unfortuntately, the metal is soft and scratches easily. Otherwise, I’ve had no real issues. Got it with the $150 off sale, which you can’t really beat. Overall, I’d have to say that all tech can suffer wear-and-tear. A few scratches and $6 a month (really, guys, it’s only $6. Imagine buying a tv and complaining that you have to pay for cable/subscribtion services. This is how things work.) are worth what it does for you. I’m happy with my purchase.

    Much comfortable and convenient than I had originally thought. The ring communicates with the other health apps I have and synchronizes the data efficiently. I find it especially useful to track sleep patterns.

    I was unable to wear this ring on my index finger as it was purchased for my wife. It turns out I she is not as cool I am, and did not want it. I tried it for a week and found it to be comfortable and I really liked the different data points it gathered. More than the raw data I especially liked how the app analyzed it and then explained the scores for me. I have since traded in for the correct size and am looking forward to building a significant baseline. Not for nothing but I am also looking forward to the integration with dexcom and their CGM. I feel like that elevates the Oura 4 to the top of the food chain when it comes to wearable tech for health purposes. When and what to eat along with sleep to maximize metabolic health. Excited to get the full experience from this product.

    I love this ring! I have some medical conditions that I deal with and it has done a great job helping me manage things, especially my sleeping and my stress. The battery life on this ring is awesome as well. It will last over a week.

    I’ve owned OURA rings for a few years. The Gen 4 ring has made a number of improvements. Longer battery life, lighter weight and an updated app are a few of the new features. I am very happy with the OURA ring and start out my day checking my data.
