Customer Ratings & Reviews

Essentially free since you get a $10 best buy gift card, and the kit definitely lets you know which ring fits best, the rings themselves are almost the same weight and same thickness.

Great product to get the right size for your Pura ring! Would prefer to try on in store instead of buying.

I highly recommend getting this before purchasing an Oura. You can see if it will actually work for you, and get the correct size. Adtually free as you get a gift card for Best Buy when you purchase it (well, at least I did)

The sizing kit was super helpful before ordering the real ring. It let me try a few sizes and find the perfect fit. The plastic rings are comfortable enough to wear for a day, and it made the final purchase stress-free. You also get the money back which is a plus.

It did what it was supposed to do but after using the sizing kit, it became just more trash and plastic garbage. Why not just have the sizing rings at the store display to minimize waste?

Will need this to know what size oura ring to buy. Wear ring for a few days becore deciding what size ring to order. Best Buy gave me a $10 gift card with purchase.

Sizing rings fit exactly the same as the real ring. Basically free too since you get a 10$ gift card

Very helpful in determining what size you need. Recommend wearing the sizer for an extended amount of time to make sure you get the right fit. Found it to be true to size to the actual oura ring, but the sizing runs small compared to tradition ring sizes

Great for figuring out size to ours rings. Easy to use.

Very helpful for finding correct sizing. I was between 2 sizes so wore both for a week to see which one felt best. I also watched a few YouTube videos that helped to inform me if you're between 2 sizes to choose the smaller size. Sizing will definitely depend on the finger you intend to wear it on, and whether you plan to always wear it on that finger or switch between several fingers. This kit was perfect for testing out the size before making the bigger purchase. Helped me choose the perfect size!

The sizing kit arrived really fast and makes it so easy to size your fingers for the Oura Ring. I am so glad I ordered the kit!

I wore the size 12 and 13 plastic rings for a few days to see which ine worka best for me. During the day my fingers swell a bit delending on what im doing so I found myself rotating these plastic rings on different fingers while I went through my normal routine. They are just small plastic rings, but they give a good example of what the actaul Oura ring is like.

This is a great kit to have when you are trying to decide what your ring size is when purchasing an Oura ring since they do not follow typical ring sizes. I would also recommend getting this because you can take a week or so wearing different sizes to see what size is best for you and to figure out how it feels in different scenarios. It also comes with a $10 best buy gift card so you are technically getting it for free when you go to purchase the actual Oura Ring.

I loved this because you can keep it not only for yourself but if your friends or family needed to check to see what size they wore, you have the kitten hand for them to size their finger at first I thought I was wasting $10 but then I thought about it and thought it was a great investment to have a ring sizing kit For not only myself, but my friends and family as well

So glad I got the kit. I thought for sure I knew what my size was, but I was wrong. This worked out great because I was able to get my money back for the kit when I purchased the ring. I felt more confident in my purchase. I also let my husband try the ring size kit, and I’m going to let a friend try it out next week.

I love the fit test kit. When I got my ring, I knew exactly what to expect. Without it I might have gotten the wrong size because of the 3 bumps inside. If you are considering getting an Oura Ring, highly recommend getting this kit to know the proper size. A normal ring size kit will not account for the bump spacing for the sensors

This was a perfect no-risk way to find the Oura Ring size that would work best for me long-term and in different environmental conditions. Rather than wear the sizers for 24 hours as recommended, I wore the sizers nonstop for an entire week, doing all of my typical activities, and in varying weather conditions (including some of the hottest, most humid days of the year!). This enabled me to assess comfort and fit throughout each day, and to determine if swelling would be an issue. The upshot of this purchase was that I decided that a smart ring would be in my future definitely, but perhaps not the Oura Ring after checking social media and BBB reviews (I couldn't find any on the Oura Ring website). The gift card that I received after purchasing this kit will be used towards another product, but if reviews of the Oura Ring and customer service improve, I'll happily go through the sizing process again with the kit I have. It's a win-win!

I bought this to see which ring size would be best for the Oura Ring. It was very helpful in determining the size but I do wish they also included half sizes for each. One is too big, the other almost too tight. My purchase of the real ring is still pending as a result. Overall though, great idea so you do not make a mistake when purchasing the real one

The sizing kit was nice to start off with so I could try several different sizes for a full day. This way I knew the exact size I wanted to buy when it was time.

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!!
