    This was actually a gift for my daughter, and she loves it. It is great for keeping track of her sleep patterns among other things. She already recommended it to her friends, co-workers, family and her boyfriend. Needless to say, she is very happy with this gift.

  • Gen 4 falls apart! Lots of reviews out there….

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

    I was excited to get this ring for Christmas. I went to hockey with it on (Oura site specifically says it’s ok for hockey and it is listed in their app). 20 minutes into skate, I feel a looseness in my glove and the ring was in 4 pieces. Inner ring, outer ring and two seals. Unbelievable. Looked around online and found MANY reviews and instances where this has occurred, even while doing something like washing their hands. Mine is returned. App deleted. Junk. DO NOT BUY GEN 4!

    i loveeeeee my oura ring! it’s so easy to set up, the instructions for how to best use it/charge it/how it tracks are so easy to follow. and if you have any questions, the app itself makes it so easy to find the information you’re looking for.

    Does what its supposed to. Good battery life. I just recommend you actually buy the ring sizer and use that for a day or two before making your purchase.
