    I was so pumped to get my Oura Ring Gen 4 for Christmas from my family! It was awesome. I did get the size kit before I told my family the size but the size 10 was much bigger when I got the actual ring. I was so impressed with Best Buy Customer service who helped me get the right Oura ring to exchange my size 10. My size 8 came in 2 days. Thank you!

    This ring is awesome as long as you go into it with proper expectations of what a smart ring was originally designed to do. Definitely get brushed silver, though, because it is the only one that hides scratches well.

    The ring is a good ring and seems to monitor a lot of health issues. I just dont understand how to read all of the info on the app though or how to set certain things on there. I guess i will learn as time goes on. There really should be some sort of tutorial with all the different things on it so that I can learn all the different functions. I really thought the battery would last a little longer though i seem to only get about 5 days out of it.
