Customer Ratings & Reviews

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.

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.

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.

The product was helpful in deciding what size to get. I also used the sizer and pretended it was the real thing to see if id get uncomfortable wearing it since I dont wear jewelry often. I also wore it to see how well id keep track of the real thing once I get it.

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.

Ring sizing kit is necessary for an accurate fit. OURA ring sensors are sensitive to correct measurement. The in-store free measurement is wrong. This cheap kit will prevent the hassle of returning/exchanging the wrong sized 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

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.

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.

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!!

Oura sizing is a little different than standard ring sizes so this is a must. Wearing the sizer for a few days helped me get the perfect size Oura ring the first time. Plus, with the $10 gift card with purchase, it is essentially free - highly recommend if you are in the market for an Oura.

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.

If you’re planning to buy the Oura Ring, this is a must! Sizing is so tricky im normally a 7 and ended up going with a 9. Definitely try it out for a few days before making a decision.

Worked well for what I needed. Just needed to figure out oura ring size. I ordered the exact size it recommended after wearing the sizer for a day. Fits great! Recommend if you’re unsure of your oura ring size.

Worked great and helped us ensure we ordered the right size Oura ring. We ended up ordering a ring for my wife, so I'd say the sizing kit was a success and converted us into customers. That and all the raving reviews from friends with Oura rings.

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 kit was helpful. I wore the sizing ring for a week to really get a feel for the ring. For the price of the ring, this sizing kit is worth it. I received my ring and I'm thrilled. The ring is comfortable and doing its job.

Sizing worked great - nice that if you happen to be buying Oura rings for multiple people, each can try different sizes. Ended up ordering Ouras for my wife and I after wearing the sizers for about 2 days.

This was great! I wish Best Buy let you rent them bc I don’t really need it now that I’ve used it, but it’s great for testing the sizes!

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.
