    This helped so much with choosing the right size oura ring. I was set on a size and decided to try this just in case and ended up being wrong and going with a smaller size.

    This was very helpful in determining my correct ring size. My daughter ordered an Oura ring using the samples at the store and it was the wrong size so this was very beneficial for me when I ordered my ring. It was also a plus that I received a $10 gift card with the purchase of the kit.

    I did get the ring sizing kit to make sure I had the right size this time. I am returning the larger size. Too big even though I tried on at store.you buy kit for $10 and then you get a gift card. So you really are not paying for the sizing kit
