They work great for any size ring
These are perfect. Theyโre strong and solid. They come in a variety of sizes in one pack so itโs easy to find the perfect fit. The clear ones are nice because nobody ever notices theyโre there. Theyโre essential for me because my fingers change size depending on the temperature. I canโt even feel it. I donโt ever even remember itโs there. They donโt stick, they pop into place which is nice. All I had to do was put the ring on just past my knuckle and snap it onto the ring. Took me about 5 seconds and I was all set. Iโd recommend these to anyone whoโs worried about losing their ring because they cost next to nothing compared to losing an important ring. Worth it.

Sleek, hidden, and comfortable
These worked perfectly for us! My husband used one on his wedding band and he loves it. It gives just the right snug fit without changing how the ring looks or feels on his hand. What I really like is how sleek and hidden they are. You canโt see it once itโs on, and it doesnโt make the ring look bulky at all. Way better than those wrap-around style adjusters that are noticeable and uncomfortable. Simple, effective, and super comfortable exactly what we needed.

Measure measure measure
Good idea, but did not fit the ring I bought it foreven though I measured it with a caliper. Bonus, one size in the package fit another ring. So Iโll mark it as a win.

Not great for a thicker menโs ring
Seems like it would work with a skinnier ring. The ring we want to use it on is a thicker menโs ring and it doesnโt stay on right. Only the thickest one would fit the ring. As you wear it, it kinda slides off each side. Would probably work better if it had some sort of adhesive on it the inside. Itโs comfortable and doesnโt irritate the finger.

Works fine
These work very well. Had to buy them for my husband's ring since he lost weight after the wedding and his ring is a bit small. Don't forget to use the double sided tape to stick it to the ring though or it will slide around and be uncomfortable.

Product falls apart from the ring in a short period of time.
This product comes with 2 each of four different sizes. When you determine the correct size for your ring, it snaps into place nicely. BUT the first one that I put on lasted only 11 days and the second one only 10 days before I noticed that they were gone from the my ring. They can't just come off as a whole unit while you are wearing the ring so the part of it that clips to the edge of the ring must break off, allowing the rest of the ring size to come off. I would not recommend this product.
