    The ring looked nice at first and the design is not bad, but after just a couple of weeks the color changed and it started to look worn out. It also got many scratches very quickly, even though I was careful with it. Unfortunately, the quality didn’t meet my expectations.

    The Oura ring is amazing keeping you informad about your health and habits. The app is great, and tells you how to improve your health. The only think I will have to deal now is the warranty since the battery is lasting a day and a half after less than 10 months of use and it was lasting 4-5 days.
