Fantastic way to try something before you order it!

Remarkable sizing system for the Oura fitness rings.

The kit pays for itself with the girftcard. Gives you a chance to see how it will feel.

Great product to size the oura ring. It worked out perfectly.

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.

Very good and accurate ring guide was very useful in picking the oura ring, since they tell you to wear it on your index finger, it a much different size than the ring finger for us.

Great way to get the right fit before purchasing the ring.

Oura ring sizing kit was necessary to decide on the appropriate ring size as this size varies from normal sizing.

perfect fit before buying the OURA ring - good invest

Highly will recommend getting this before purchasing the real deal that way it saves you the hassle of returning it and you will have the felling on how it feels on your finger

Helped with finding the perfect size for the perfect ring for my sons

I’m glad I got the kit because I was almost certainly going to get an Oura ring until I tried one of these on. I’m relieved I didn’t spend $500 on a bulky ring that I would’ve hated wearing.

Helped me to determine if I wanted the gen 3 or gen 4 and what finger id want to wear it on and what size to get!

I bought this to get the sizing for the Oura ring. Was nice to get a $10 Best Buy reward for this item and ended up using it towards a ring. I wore the sizer for several days to make sure it fit without ever getting too tight or too loose.

Ring sizer is easy to use and worked for me. Definitely worth testing out a prototype ring before making a purchase

If you are planing on getting the Oura use the zing kit and try it for a few days o see what works before buying the actual product

A must before buying an Oura ring but it’s not exactly the same as an Oura (I had to exchange my Oura ring for a size smaller when the ring I bought would fall off my finger when my hands were wet (same size from the sizing kit had no issues).

They are pieces of plastic that replicate what each ring size would feel like. I found it very helpful because no variation was comfortable for me and I learned the Oura is not for me.

This product was very helpful when trying to determine my ring size. I liked that the models were of what the real Oura ring would feel and look like! Very helpful when trying to find the best fit!

Great product!! Just a described and really comes in handy. Great deal also.
