    After 3 months of use my oura ring all of a sudden expanded and it no longer fit in the charger and on my ring of course. It also doesn’t communicate with my phone anymore. Seems like the battery swole up which is actually scary cause it could’ve happened while wearing it and gotten stuck in my finger. I submitted a warranty claim and after 20+ min with talking to a rep, they now sent me a questionnaire for troubleshooting. Such a mission - I just gave up unfortunately. What a waste of money. Will never purchase it again.

    Love the ring and the technology but I returned because after 3 weeks it already had a significant amount of marks in the gold. I knew after a few months it wouldn’t look good so I returned for a ceramic one! Still waiting on the one

    I got this ring for my wfe. It is a very cool product but the only thing is that you have to be aware that after more than a year, it can star failing on taking data and getting charged.

    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!

    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.
