    Ring completely expanded - such a waste of money!

    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.

    Very impressed with the metrics this collects. I have this alongside my Apple Watch and I feel this has helped me track my Menstrual cycle in better predictions and gives me great insight about my rest and recovery after sleep. I only subtracted 1 star because it requires a mandatory monthly subscription but otherwise fantastic tool for health insights.

    I bought my Oura 4 ring in April 2025. I loved how it tracked my walking and other exercises. However, over the last few months, the ring no longer automatically detects them. What happened? Customer support is by chat and has not been very helpful.
