A: Hi, thanks for reaching out about Oura Ring 5 Sizing Kit.
The Oura Ring 5 mainly builds on the Oura Ring 4 with incremental improvements rather than a complete redesign. Differences typically include enhanced sensors for more accurate health tracking (like sleep, heart rate, and readiness scores), improved battery efficiency, and updated software features/algorithms for better insights. The overall look, size options, and general functionality remain very similar, so sizing kits are used in the same way for both generations.

The product offers a variety of sizes, making it easy for guests to find their fit, but some guests have experienced issues with missing sizes and difficulty in removing the rings. While the kit is appreciated for its helpfulness in determining ring sizes, there are concerns about the comfort and usability for those with larger fingers. Overall, it serves as a useful tool for confirming sizes, but improvements in size range and comfort are desired.

Seal on kit was broken already and one of the sizers was missing. Not sure how since this product is supposed to be non-returnable.

TARGET CANCELED THE GIFT CARD BUT SHIPPED THE KIT!
SHAME ON TARGET! I purchaseed this sizing kit because Target offered a $10 Gift Certificate with it. AFTER my order shipped, it showed that Target CANCELED the Gift Certificate! They make it impossible to reach Customer Service and I cannot return this because it's not returnable. DO NOT BUY THIS KIT FROM TARGET! Totally FALSE ADVERTISING! As for the Kit..I have the Oura Ring 3 and although Oura said that this new Generation would fit differently, I wear the same size and the ring from the kit doesn't fit any differently than my current ring.

okay sizing kit
lots of sizes but not for fat fingers. biggest size slid in nice but it was so hard to take back out. the ridges inside cut up my finger/skin. I'd love to see a range in sizes, I know size 13 is their biggest they offer. some of us fatties wanna be on a journey to healthiness

Easy and helpful
This was very helpful in determining my ring size. It arrived next day, which was very fast. I do feel that the gen 4 fits me the same as gen 5, but it was important to confirm that since Oura shared that sizing would not be the same as previous rings.

I received the kit for the Oura Ring 4 and got no help exchanging for the actual Ring 5 sizing kit.
