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.
