    The ring fitting within the store was easy to navigate. My ring fits perfetly and the battery lasts a few days. To charge, it only takes about an hour. The OURA app is easy to navigate to get stats on your heartrate, stress, lseep patterns, excercise, and more. Highly recommend if you're interested in seeing more/ keeping track of your vitals. Note that the silver does scratch.

    This was a gift for my wife and she loves it. Just make sure that you get the sizing correct because it differs from normal ring sizes. The associate in-store was able to help us get the right fit.

    Love my Oura ring. Battery life is fantastic, and it charges quickly. I forget it’s even on my finger, it’s not bothersome like some other options for health tracking I have tried. The monthly fee is minimal and well worth it.

    Does most of what the Apple watch does yet it is much smaller (easy to sleep with, etc) and the battery last about a week. I'm very happy with it and would have given it 5 stars if it wasn't for the monthly/yearly charge. Most other rings like this don't have that charge.
