Customer Ratings & Reviews

Glad I got the sizing kit. In store I thought I needed a different size, but wearing the trial rings at home at different times & temps made a difference in the ring I ended up purchasing. Definitely worth doing the trial

This ring sizing kit is wonderful to have handy and having it can help you to make sure your purchasing the right ring size. It's of excellent quality for sizing rings and will last if it's taken care of.

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.

If you plan to buy an Oura ring I would definitely use the sizer. I was impressed because I was given a gift card by Best Buy to offset the price that I wasn’t expecting.

Really happy that i stopped by the store to pick up a kit. The actual ring size differs slightly from the one in the sizing kit. Not by much though, but it’s very helpful to finally know and understand my ring size after 30 years!

This sizing kit was great, as the Oura Ring is a few sizes bigger than your normal ring size. I am usually an 8, and am a 10 with Oura. The ring fit exactly like the sizing kit when it arrived.

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.

Worked perfectly, to measure out my finger to figure out the size needed for an oura ring

I would buy this to make sure that the ring size you get actually feels okay. The in store display sizer is okay but a little different that the to scale rings from this set.

This item is very well made and most importantly, very accurate in sizing, which I really appreciate. I highly recommend.

Very accurate for sizing purposes. Great way to figure out the best size for the best finger.

Very nice product happy with it different sizes and excelent

Pretty easy and convenient sizing experience. I spent a few days testing out different fingers so that I could confirm which one was best for me before I submitted an order for a full ring.

Fire purchase, i have no regrets at all and works like a beast. I definitely recommend to anyone who is hesitant or wants to purchase one. This one is great

Essential! I initially thought it was unnecessary, as I had tried the ring in on the store. I ended up getting a different size than I thought I would need. So helpful! Must have!

I was just going to take a chance on my ring size, but I’m extremely glad I got the sizer. The ring ended up being two sizes smaller than I expected, so this saved me a trip to the store and the headache of returning. This was helpful-definitely reccomend

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.

Definitely a must get before getting an oura ring. Wanted to see what my size would be before buying an oura ring and I’m glad I did because the size I thought I was ended up being to tight.

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.

i thought it was pretty accurate to the size ring i bought
