Customer Ratings & Reviews

I would highly recommend getting a set of these before purchasing the ring itself. They were helpful in knowing figuring out which finger I was going to wear my ring on and the correct size to purchase.

Gotta say a must have before getting a oura ring. Has all the sizes to try on.

This is such a good idea. Will see if the wife decides to actually get an Ōura Gen4 ring or not, but the ten bucks is wort it to get her an idea of the right size, which finger, and get familiar with the features she could have. And, if she does choose to get one, the ten bucks gets applied to the purchase. Wish me luck!

Ring size kit was great to be able to use prior to buying an Oura ring. I definitely recommend getting this rig size kit before you order a ring. Plus the kit is Free so you might as well get it. These ring sizes are different from jewelry.

Straight forward and simple, did exactly what it was supposed to do and easy to follow instructions. Quickly available, and what I was specifically looking for. Thats about as good as it gets.

Perfect to help get the right size ring that you need. Does what it is supposed to. Great sizer. Would recommend to anyone that is going to buy an Oura ring

The Oura ring sizing kit works great. It's accurate and fits fine. Highly recommend before buying the actual ring!

Is exactly what it says it is, and helped me figure out the right ring size for an Oura.

Definitely helps with sizing on orders. Helps not to have to deal with returns.

Perfect for Ring Size for Oura. Comes with a free card. =

Perfect for finding the fit I want. I was able to keep it on overnight to make sure it’s the fit I want overnight as well.

Having this sizing kit was very useful to measure what size ring I needed. The price I paid for the ring sizing kit was taken off my total when I decided to purchase the oura ring.

Great product used to help figure out sizing good quality.

I’ve had it for a month now and I can say it really keeps me on track not necessarily health and fitness but more habits and trends. I think everyone can benefit from it. It came neatly packaged and sealed 100% new and after wearing every day I definitely have a lot of small scratches (and I take it off for showering doing dishes etc) but not visible to the normal eye

Sales rep, Paul, was extremely knowledgable and helped me choose an Oura ring 4. Explained features of the ring and completed my purchase. This employee deserves a raise.

Was able to determine accurate sizing and appreciated the gift card that went towards the ring purchase.

this kit is necessary before you buy the ring. It is nice that you get a gift card for the amount of purchase to use. It is set up well with a full range of sizes to try. The sizing rings are the same thickness as the Oura Ring so it gives you a good feeling of on which finger you want to wear it .

Worked well to find right size. Have now had my oura for months and haven’t had to adjust finger for it

This sizing kit was exactly what I needed to feel comfortable with a purchase of the Aura ring. I wanted to make sure it was a perfect fit, and this helped me do so!

This product could not be more accurate if they tried. It's the perfect ring size test kit. We got our and are so pleased with it.
