    I'm amazed at how accurate the sleep tracking is. I appreciate the health insight tips. And the battery power lasts much longer the Ring 3 version.

    I was a bit sceptical at first but absolutely love the Oura Ring. I don't like wearing my apple watch around the clock but Oura ring is simple comfortable to wear. You must suscribe to the app but the daily insights are amazing when it comes to your health and daily activities. It is not just limited to working out but also sleep quality, stress, temperature, etc. Highly recommend.

    Overall i do like the ring! Myself personally, think its a little thick. Although from my understanding it’s significantly thinner then the last generation. It charges quick and over is easy to use! I do wish there was a better way to find it when you lose it. So i use an apple watch too and tbh im more concerned hsvjng my ring on vs my watch. I will say it scratches maybe thats totally normal for rings in general im not sure. Overall its a goid product!

    App fairly easy to navigate; only have to charge every 3-5 days; did end up being a little large after started use, but otherwise overall easy to navigate and see stats.
