  • 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!
