I just got an Aura ring this week since one of my credit cards now gives you an annual credit that made (this) one free.
I wore it for two days, but struggled to get used to having an extra ring on my hand. I need to give it another go and get used to it because I’m interested to see if the data tells me anything different from my Apple Watch. I also think I could sleep with it and I don’t sleep with my Apple Watch on.
