  • Effective Ring-Size Adjuster If Adjuster Fits Ring
I tried two types of ring-size adjusters that make rings fit smaller or more snugly. One type is the silicone “noodle” that is wrapped around a ring’s band. The other type I tried are these hard plastic pieces that are inserted (fitted) inside the ring at the bottom of the band. I liked this hard plastic style for a couple of reasons. (a) This style worked if I got the adjuster onto the ring correctly. By "worked," I mean the adjuster effectively downsized my rings by roughly half a size. (b) What I really liked about these adjusters is they are nearly or completely unnoticeable if the adjuster is situated properly. While I like these ring adjusters, I don’t “love” them. (1) The adjusters need to sit firmly in the ring and that requires the adjuster to fit the band just about perfectly. I found few of the adjusters were just the right size for the rings I have. (2) It can be a wrestle to situate the adjuster correctly (firmly) into a ring. (3) The adjusters pop off (fall off) too easily. While I will continue to use ring-size adjusters, I have a reached a conclusion I do not necessarily like. Ring adjusters can be a problematic alternative to having a ring resized by a jeweler. ... show more

  • Does the job
My ring is a little more thick so the adjuster doesn’t fit snug against the inside of the ring but it does “click” onto half the band width.

  • They slide around but overall a good ring size adjuster
I’ve been wearing these on my ring for awhile. My size adjuster stays on, but does move around some when my ring moves. Although to me it isn’t really a big deal. They’re easy to put on. Overall a good ring size adjuster.

  • This one by this seller works for me
This product is soft and maleable, unlike others I have bought. I felt this one worked for me and will buy more when needed. Recommend.

  • Hard to get on
I usually wear the coils, but wanted to try these. I had too hard of a time getting them on the rings with my arthritic fingers they may work well for others.

  • Work perfectly!!!
I ordered these to adjust the size of a family heirloom ring. The ring has an engraving inside the band so it's impossible to have it resized without ruining the inscription. Also, since it's a family heirloom and will be passed on in due time, I didn't want to do anything to permanently alter the ring. These size adjusters solved all my problems. They were affordable and included a variety of sizes (I wasn't sure what size I needed) so I have additional ones I can use on other rings. The ring fits me perfectly now and, since the size adjusters are clear, I can still read the inscription and it is almost impossible to tell there's a size adjuster on the ring. If I had to come up with something negative to say I guess that the size adjusters were a bit difficult to get on the ring. However, I don't really see this as a drawback since it makes me feel that the ring is more secure. ... show more

  • I'm impressed!
It took me a little bit to try the various sizes given and figure out which was the best fit on my ring. I wasn't sure one was going to work at first, but finally found one that fit tight on the ring, but also allowed the ring to go over my knuckle. Once I found the best fit, it was great! It's comfortable on my finger and you can't even tell I'm wearing it. I had some unexpected weight loss due to some health issues that I don't think will stick around forever, so I didn't want to resize my rings. But my engagement ring and wedding band were so loose on my finger, I was afraid they would slide off. I just put 1 on my engagement ring since that sits on top of the wedding band. It keeps it from spinning and keeps both rings in place. Highly recommend. ... show more

  • They do the job!
I don't know how well it would do if you took your ring off and on. I keep my ring on 24 hours, through anything I'm doing. And that little piece of soft plastic sits there under my ring band through anything, too. You can't see it. Those spiral rubbery ones? They're so noticeable and a bit tacky looking when you see the underside of your hand/fingers. A tad bit of maneuvering to get it to sit in place under the ring band, hold it in place as you slip the ring on your finger, but once there - it's all good. I tend to think, though, that if you took ring off/on it may slip off and easily get lost. I had one under my ring for about 6 months before it slipped out somehow. That's a good chunk of time. Happily, I had one to replace it with. I bought this new pack because I'm so pleased with this option to downsize a ring that I wanted extras to have on hand (ha, pun not intended) for other rings as I continue to lose weight. ... show more

  • Great fit & very comfortable
The media could not be loaded. My center stone caused my ring to spin. I have used metal ring guards but they never last. This fit perfect, approx 1/2 size. Very comfortable I don't even notice it. Clear plastic makes it less visible. Very happy with my purchase.

  • Worth the buy
So original I had a spiral ring adjuster ( which is annoying don’t get those) it’s uncomfortable to begin with (had to get use to the feeling), it spirals out when putting the ring on or taking it off, and over time the rubber just dried up and started breaking little by little. So I came upon this and originally I was skeptical due to mixed reviews but gave it a shot considering it looked more comfortable and assuring than a spiral ring adjuster. Yes I agree it’s a little challenging at first in putting it on, trick is start with one edge placing it sideways then push slide it in place. It worked for me compared to what I assume a lot of us tried to do by going under the ring and pushing it in. So far it’s comfortable, seamless, and just make sure you put the right size or it’ll not work out. Hope this review helps🤗 ... show more

  • Discreet, Versatile, Simple / Added grip & shorter length would be helpful
These are SO helpful! I have been really bummed out by my beautiful engagement ring not fitting...my knuckles are larger than where my ring sits, so I cannot have my ring sized down any more if it's going to fit over my knuckle. Once my ring makes it all the way onto my finger, it is very loose and flops around. These ring size adjusters allow me to put on my ring and THEN tuck in the adjuster to keep it in place. This is exactly what I needed as opposed to an overall ring size change (I would not be able to get the ring over my knuckle if the adjuster were attached to the ring BEFORE slipping it onto my finger). My only critiques for improvement would be: -Perhaps if the inner portion of the adjuster had a tiny bit of plastic tread/grip, it wouldn't slip around quite so much when wet. The adjuster fits rather snuggly to my ring, thankfully, but I think water tends to make it slippery enough to slide up around either side of my ring and become visible. -Also, it could be nice to have some slightly shorter adjusters that have the flat wing edge on it (I don't like the look or fit quite so much when I cut the edges off-I have a very small ring size, only 4.5, so the length is a bit long for me and the wings help to keep it in place, I think) Thank you so much for this product! I can finally enjoy my ring as much as a gal should be able to during this joyful time of celebrating engagement! ... show more
