vital for smart ring

LJuly 15, 2025

This set of sizing rings is helpful for finding the right fit before ordering a smart ring. The plastic bands are lightweight and clearly labeled, making it easy to test different sizes throughout the day. They simulate the feel of an actual smart ring closely enough to get a realistic sense of fit during normal activities. The material is basic and not intended for long-term wear, but it serves its purpose well. The set includes a good range of sizes and is simple to use. For the small cost, it offers good value and can help avoid the hassle of returns. Read more

Great set & I do recommend, but no ring small enough to fit my pinkies.

KizskiAugust 12, 2025

Great Ring Sizer set! Love it! I love buying rings on ebay, so with this, I can get the correct size instead of having to buy 2 sizes before I get the right size. I like the fact that the rings are wide, because this will ensure that the ring won't be too small. If anything, you may get a ring that is too small because of the thickness. But that's better than too small, because too large, can be fixed with a ring size adapter. They should have some smaller ones because I cannot get my pinky sizes although most people don't wear rings on their pinkies. But for a smaller person with smaller hands, these will not be enough. Even though it does not have small enough sizes for my pinkies, I'm very happy with this and would definitely recommend! Read more

A sizer you can wear for a bit to judge your ring size!

OwhilloJune 5, 2025

These really do work well. Always wondering what is my ring size when I go to order a ring. I’ve tried the papers and the ruler method and it just never seems to work right. I like the ring sizers that come on a key ring type circle, but this is cool because you can actually wear the ring for awhile to check how much your size changes through the day and that might make the size ring you buy change by half a size up or down. They come in a nice white box so will tuck away in your drawer to stay orderly. They are a little thick, so not super comfortable, but that’s not what I’m looking for when I’m looking to size my rings so I really appreciate having these! Read more

You might want to get a different kit if you have wide fingers. Here is why ..

Glenn H.May 2, 2025

I ordered this Weyrinice ring sizing kit since I was thinking of getting a smart ring to track my vitals. This kit did come with information which helped me determine that this was not the kit I should have ordered. The ring sizes provide in the kit include sizes 6, 7, 8, 9, 10, 11, 12 and 13. I learned from reading the box that it is recommended that a smart ring ideally should be worn on the middle finger which would be fine for me. The problem is that the 13 ring is too tight. Maybe a 14 might work but this kit doesn't provide a size 14 ring to try. I did find that smart rings for health are available up to size 14, and some of them sell ring kits that include a size 14. That said, if you think your index finger could be thicker then 7/8" of an inch or size 13, then you may want to get a different kit to insure that you have a size 14 to try. Read more

Made smart ring shopping way easier

2littlepeasMay 20, 2025

I am planning to buy a smart ring soon, and this Smart Ring Size Kit took all the guesswork out of it. It’s lightweight and accurate, and I got confirmed a size 7 for my left index finger. And for the price, it is absolutely worth it. Saved me the headache of ordering the wrong size and having to go through a return. Can’t recommend it enough. Read more

Accurate sizes, but rings don't stay put in the box during shipping.

Hunter RutzJune 2, 2025

The ring sizes aren't numbered, on the rings themselves, which would be immensely useful since absolutely none of them where in place when the box arrived. They were all loose and strewn across the inside of the box. Even so, it was easy enough to sort out the sizes. I got this because I no longer fit into my wedding ring, so I wanted to get the same ring in the correct size. From this kit, and 11 fit me best, so I ordered a ring that was an 11. The ring came in and it fit perfectly. While I don't have a caliper to measure the dimensions of these, I can say it is accurate enough. Read more

Easy solution and affordable

Jim Morton ( wchimesjim)May 16, 2025

This is a simple set of finger ring sizers. I had forgotten what my ring size was and this was an affordable way to find out and to keep them around for when I forget again. 😅 It doesn’t handle half sizes, but I imagine you can tell if you’re a half size by using the whole sizes included. It works for me . Read more
