What a great concept!! The sizing kit takes all the guesswork out of gifting an Aura ring to my wife for Mother’s Day. We used the sizing kit and ordered the ring and she is obsessed with the ring!!! The $10 free gift card to cover the cost of the sizing kit is a nice touch!!

It’s a solid sizing kit. Of course, after buying it I decided against buying an Oura, but I was able to easily determine my size. I actually wore the sizing ring for a couple days just to be sure it was the right size. The nice thing is that it just looks like a black ring so no one will know you’re wearing a plastic sizer, lol.

Sizing kit is extremely accurate to the actual ring sizing. Was easy to to determine size and try for a few days and nights before determining what size to buy. Would 100% recommend using the sizing kit before purchasing your Oura ring.

The Oura Ring Sizing Kit was easy to use and very accurate. My ring arrived and the sizing was perfect! I also like the fact that it's inexpensive, but the bonus was receiving the gift card that made the product free. I'm loving my Oura Ring!

Was interested in the Oura Ring and needed the sizing kit before purchase. Worked very well, and a gift card toward the purchase of the Oura.

If interested in buying an oura ring the sizing kit is the best way to go. Yes there is a sizer in the store but with the kit you have interchangeable rings to use in case your fingers swell over time and you can wear the rings all day to test out the fit.

100% recommend buying this before the ring. This allowed me to wear the tester for multiple days and to bed. It allowed for my finger to swell and test different sizes. I love that best buy gives you a $10 e-gift card to use towards the ring purchase.

Easy to use for fitting of Oura ring! Came quickly but not sure how to recycle. Wish they had a recycling program for these.

Highly recommend to make sure you get the right size before ordering the ring.

Just what i needed, never could order a ring without it, would recommend for yourself and anyone you need to know their size

I was certain of my ring size. I stopped by the store and to my surprise the measurements were not in US standarding sizing. I also felt like I needed a half size which is not available. I purchased this set to not only make sure I choose the right size but to also wear it. The actual ring is expensive and I wanted to be sure I liked the size but also the fit. I've worn it daily for 2 weeks although Oura says you only need a day or two. Also both my husband and son have been walking around with one as well and Oura is now on all our Christmas lists. Also with Best Buy's $10 gift card with purchase the ring sizer ends up paying for itself even if you don't decide to purchase the ring.

I bought this to get the correct size for my oura ring and I’m so glad I did the sizes run different then my normal ring size I’m normally a size 7 but with this I was a size 9 so I ordered a 9 and it fits me perfectly

I buy the 4 generation oura ring, I use the sizing kit for Gen 3 and it works well to choose my size.

Definitely get this to size the right Oura ring, without it you are playing a guessing game since the ring size doesn't correlate to a regular ring and it's recommended to wear it on the pointer finger.

Would 10000% recommend to anyone who is looking to buy the Oura ring! The sizing of these is way different so being able to try multiple sizes out and wear them throughout the day to see how it feels when your fingers get bigger and smaller throughout days and night.

Extremely useful - Not only made the sizing decision easier, I was also able to wear the model for a few days to make sure I was comfortable with the ring in my day to day. This ensured I was not only comfortable with the ring, but that it was easy to adapt to.

Using the sizing kit I was easily able to figure out what size of ring to buy. I am very satisfied with my Oura Ring!! :)

Set arrived in good condition and on time. Sizing was a snap, just pick the one that fits and slip it on. Added benefits to this are you can try different fingers to see which one you want to wear it on and you can wear the sizer ring for a few days to see if it will inhibit daily activities.

This is a very nice set for sizing your ring size. I ordered the Oura Ring from the website and confirmed my ring size. I am confident that the ring will fit when I receive the ring. Would recommend and would buy this sizing again.

Nice way to check ring size for oura. I bought this since i heard oura rings are sized differently than regular rings. It has many sizes to try on and tells you which size to pick based on how it is meant to be used with the way oura works.
