do you buy used smart rings?

I want to buy oura smart ring but I dont want to buy a new one because its too expensive for me and I was wondering if its normal to buy used oura ring?

could used smart ring affect the accuracy of my health isights? is there a way to reset the smart ring so the device would forget all the previous health info from the person who was wearing a ring before me?

how does it work and has anyone bought used smart ring?
