  • BUYER BE AWARE -- battery life degrades in months

    the battery life was a week -- now it is less than 2-days, and it has been 7-months of ownership. I have been very careful about battery life, as I own a Tesla and understand Lithium care.

    Stopped picking up heart rate - Followed all their instructions to fix but nothing worked and now they say it is not their fault. Bets Buy says there is no warranty which I thought was illegal in NYS.

    I liked it, but my fingers swelled. I tried both sizes 8 and 9, but they still felt uncomfortable. The ring didn’t detect my sleep accurately, which was the main reason I bought it. So, I had to return it.

    The ring will not connect to my son's phone and Oura Ring customer service has been useless in getting it fixed. Now it's too late to return and I'm stuck trying to sell it.

    Great ring

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Wanted something that would track my sleep and health. Does more than expected. It’s comfortable and discrete. I wear it on my wedding ring finger as I don’t like the bulkiness of smart watches. The battery last a full week.

    Upgrade from gen3

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I switched from the gen 3 and so far im enjoying it. Battery is about 6-7 days, and it seems more accurate than the 3. I like that the sensors are flush and dont stick out like last gen and it seems more scratch resistant
