Customers are saying

Customers are impressed with the Oura Ring Gen3 Sizing Kit's accuracy in determining ring size, with many reporting that the recommended size fit perfectly. They also appreciate the ease of use, describing the sizing process as simple and straightforward. Additionally, customers value the $10 gift card that comes with the kit, considering it a great incentive and essentially making the kit free. On the downside, a few customers found the plastic sizers uncomfortable to wear, especially when gripping objects.

    It’s been brought to my attention that the sizing kit is a wee bit smaller than the actual ring so I’m glad I ordered this before I got too into my indecisive tendencies and just purchased the ring based upon Reddit’s sizing comparisons and reviews alone.

    Did the job that it was supposed to do. Very wasteful though as it's a "use it once" situation.

    These affordable sizing rings are a safe bet. At the moment, there is a store credit offered for the same amount for future purchase.

    I got this kit and used this kit and yet the ring I ordered fit differently than the plastic sizer. the plastic on the ring is more rigid and does have some impact (ring still fit but fit smaller).

    No, I would not recommend this to a friend

  • Well packed set of sizing rings

    Well packed set of sizing rings. I would suggest larger font for the printed sizes, though. But I get it, that every company wants to look premium :-)
