Read the listing extremely well. Says it's the ring then in parentheses at the end says it's the sizer. Read more

I got the Oulencu sizing kit before ordering the smart ring, and I’m glad I did. Their sizes don’t match standard rings, so using the kit helped me find the exact fit for my index finger. It’s simple to use, and the instructions are clear. The ring fit perfectly when it arrived, and I haven’t had any issues with comfort or tracking accuracy. Definitely worth getting the kit first—it saves you from guessing and makes sure you get the best experience with the ring. Read more

set of ring sizers seems to be accurate. I tested it with a few rings that I and others have and the sizer confirmed the sizes we wear. The only drawback is that the smallest size provided is six. I wear a 10 on my ring fingers, but my partner often needs a five or 5-1/2 for her other fingers. For the low price, though this set is well worth having on hand (excuse the pun). Read more

This Oulencu Smart Ring Sizing kit is perfect. The first ring I ordered, I used the Oura sizer while at Target. The Oura sizes are way different than any other Smart Ring. I ordered the next ring using the string/paper method. Either I measured wrong, or the sizes they give you run big. I finally gave up and ordered this sizing kit. It gives you a much better idea of what size you need. It also makes it easier to determine which finger the ring will be most comfortable on. You are supposed to wear the sizing ring for 24 hours before ordering the actual ring. I couldn’t decide on which finger, so I wore the sizers on both of the fingers I was considering. I found that on one of the fingers, the ring got in the way of normal, everyday activities. Decision made. It is definitely worth the money to order a sizing kit before choosing a smart ring. This Oulencu smart ring sizing kit seems to be sized for most of the “off-brand” smart rings here on Amazon. Since the big name brand smart rings don’t have the features I wanted, this was the right one to order. The smart ring I ended up ordering came today. It fit beautifully. Read more

Very good Quality, ease of use. Accuracy Read more

These work great. I really didn't know my ring size anymore and was looking at one of those fitness tracker rings. My spouse is, too, so i figured this would work well. There are eight sizes, and work great, even if you have bigger fingers like me. Now, we both know the sizes of all of our fingers. So, this is well worth it. I think the price is nice. This is just for the sizers, just in case the description is confusing. Overall, I am happy with this. Read more
