They are a tad difficult to get the plastic tab through, but worth the hassle
I still have on 2 of these ring sizers on that I put on the day I got the order & I love them! I do wish they had more of the same size, but I understand people need a variety. I will be ordering another box so I can get more of the smaller ring sizers. Like I stated earlier, they are a tad difficult to get the plastic tab throught properly, but I am a determined person & if I can get them to work, anybody can. LOL Of all the ring sizers I have purchased, these are the best so far.

Ring guard
I bought these hoping it would fit my ring but they all were too big in sizes and I had to return them. They were easy to use but just didn’t fit for my ring.

Great ring sizer
Took some time to figure out how to use but once I did it works perfectly. Some people have complained that it hurt their finger but I wonder if they followed the directions and trimmed the sides if needed. Once I trimmed the sides, I didn’t feel the ring sizer at all. Best of all it is not bulky like the coil types and it is hardly noticeable.

Not easy to put on rings But Coil Was OK
Found the majority of what was in the kit essentially useless - way too hard to attach to rings....But the pieces of coil that were in the kit worked perfectly. Recommend going with a different product that has the coils only.

Perfect
It is the best ring reducer so far. It doesn't come off and makes my ring fit perfect. It does shift on the band a little but best product by far.

Great Product!
The ring sizers are incredibly user-friendly, allowing anyone to adjust their rings with ease. With a wide range of sizes available, they cater to all types of rings, whether delicate bands or chunkier styles. I wholeheartedly recommend this product for anyone struggling with ill-fitting rings. Once you’ve inserted the sizers, they seamlessly blend into the ring, making them virtually undetectable to the eye. Moreover, they offer a snug fit without compromising comfort, enabling you to wear your favorite pieces worry-free throughout the day.

PITA Product!
These look good in pictures, but are a complete PITA to put into any ring. Just as well, they are extremely painful on the underside of your finger as they are a harder form & thicker type of clear silicone. You're better off going with the old-school telephone type coils for the bottom of your ring as they are painless on your fingers, comfortable on the bottom & easy to remove & replace on your ring if you need to clean the ring itself or to remove the ring at any rate!

a temporary but good fix
I lost weight and am still losing but wanted to wear some of my good rings. I didn't know if these would work but they did and now I can wait until I finish losing to get them resized by a jeweler. A temporary fix but it works. The product is easy to use (just takes seconds) and sturdy. Definitely worth the low price.

Fairly simple to fit
My daughter fitted one of these adjuster's to my wife's ring and it is now a perfect size, lessening the chance of it accidentally falling off.

Unreliable product
Unfortunately the adjusters didn't fit snuggly enough for me to put the ring on without turning it or putting pressure on the ring until it went over my knuckle. They are very uncomfortable, after cutting the adjuster (following the instructions) to size it would stab my finger. I used 2 from the pack which both snapped.

Not great
These are not very comfortable and reduce the rings size a bit too much for my use. They may work on rings that are much too big but if your ring is only slightly too big then they cause discomfort and are able to be removed too easily.
