Helpful tool
I needed this to pick out a ring online, way better than using the string method. It’s super easy to use, comfortable to wear and it’s something that’s good quality so you can keep it. If you need to size a ring for someone else or even to redo your own size. It is very easy to use and small enough to store anywhere. It isn’t flimsy at all and feels like a solid piece

They work and seem fairly accurate.
Surprisingly they are decent little things for the price. Easy to use. The measurements seem accurate enough. The raised gold markings/lettering/numbering seem nice n durable. Can reuse these things quite a bit without degrading the appearance. Overall a good product for the price.

Cool little product
It works perfectly and allowed me to order the right size ring. Super simple concept and design, hence the low price. I also preferred it over the other systems that have like 20 metal rings. This is literally a non-locking zip-tie with measurements on it. Love it!

Accuracy Issues
This is great if you want an idea of what size you might be, but it’s not very accurate. It’s cheap and easy to use but the numbers to tell you the size aren’t clear, hard to know which line is which number, and that could easily mess up your sizing by half a size.

Use the right side of the numbers
It works well as a ring sizer. You'll see that the "1" starts on the first notch, and for all the numbers afterwards, you'll need to use the "end" of the number for the whole number, as opposed to a half. If the arrow is pointing at the "1" in any of the double digit numbers (10-17), then your ring size is at the half. For example, my arrow points at the first 1 in the number "11," so my ring size is a 10.5.
