    I absolutely love my Oura ring. The only reason I won’t give it 5 starts is the battery.it was advertised as 8 days but I get 5 if lucky and it’s really frustrating when traveling.

    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.

    I got this ring because I was trying to track my cycle to have a baby this year. The ring does not provide exact measurements you must link the data to an outside application, which also costs a monthly premium. The ring scratches VERY easily and battery dies way too often. I'd rather just take my temperature manually and use my apple watch. Would not buy again. Said I was always stressed, which I already knew from my therapist...

    Thing is cool, I don't know what I was expecting but it is great to confirm that my sleep is atrocious and that I am not active enough. Definitely motivating
