Rocking cheap plastic for 2 days saved me $400.

My partner made fun of me for walking around the house wearing a fake white plastic ring, but who's laughing now? Testing it while washing dishes and sleeping helped me pick the exact right fit for the Ring 5. The Walmart Cash credit applied right away when I bought the real ring, so no complaints here!

Not the same as the Oura 4!

[This review was collected as part of a promotion.] You 100% need to get this to make sure you order the correct size for your Oura Ring 5. The sizes are not exactly the same as the Oura Ring 4 and not the same as regular ring sizing. It is definitely worth it to wear the sizer for 24 hours to make sure it's a good fit for everything you go through in a day!

Good value to be sure of size before purchasing

[This review was collected as part of a promotion.] Haven't tried it yet, but it's a great way to be sure you're getting the right size for a reasonable price. I like that you can wear them for a while so you know how it will fit as you go through your day and sleep at night to ensure you are getting me most comfortable size for you.
