Perfect Fix for My Loose Oura Ring
I bought this Invisible Ring Size Adjuster to help with my Oura Ring after it became too big once I lost weight, and it worked perfectly. The adjusters are easy to put on, comfortable to wear, and truly invisible once the ring is on your finger. I love that it comes with multiple sizes and thickness options so you can find the perfect fit. It keeps my ring secure all day without spinning or slipping, and it doesn’t irritate my skin at all. If you have a ring that suddenly became loose especially something expensive like an Oura Ring this is an affordable, simple solution that works exactly as promised. Highly recommend!

Perfect ring adjuster - snaps right into place!
I have been using these ring adjusters for over a year & they don't fail! They are pretty much invisible & are barely noticeable on the bottom side of the ring. They are designed to stay in place & they don't fall off. I like that they clip onto the ring. There are a variety of sizes, but I don't use the very large sizes. I would love to see a package with 2 or 3 of the most common sizes, as I don't have wide or thick rings to use the larger ring sizers. They do not irritate my skin and are very comfortable. I hardly notice them. Good value for price. I highly recommend.

Easy to use, effective, temporary odor
I had two signet rings which were maybe 1/2 size too large to fit comfortably. Especially when my hands got cold, they would rotate to one side or the other, or slide down onto my knuckle. These adjusters are made of a slightly flexible plastic. They simply snap into place on the inside of the lower part of the ring, occupying about 1/4 of the inner circle, and effectively make the ring fit just a little bit more snugly. As far as comfort goes, I can't feel them when wearing the rings. The only way I know they are there at all is that the rings fit better than before. They are made of a very transparent plastic material, so not easy to see even if looking at the bottom side of the ring, and completely undetectable when looking from the top. Since the plastic material is softer than any metal used in jewelry, I can't imagine how they could possibly damage a ring. If you do anything that gets your hands dirty while wearing the ring, some of the dirt may get trapped under the adjuster, and be visible since it's transparent. If this happens, it's easy to remove the adjuster, clean the dirt out, and reinstall the adjuster. The package contains one of each of the listed sizes, so you will end up with a bunch of leftover sizes that you probably don't need. As it turned out, I used two out of the package, for two separate rings that had different widths. The rest are redundant for the moment, unless my fingers somehow become more slender, or someone else in my family happens to need one. At first there was a very strong plastic smell that I could notice any time my hand was near my face. It was fairly intense and unpleasant, and although I didn't have any allergic reaction on my finger (no rash or itching, no discomfort), some sensitive people might. The smell lessened, and eventually went away after a number of weeks wearing and washing my hands with the rings on. I suppose someone could leave the ring in a dish of warm soapy water for a while if they didn't want to wear the ring with it smelling so strongly. Overall, the adjuster does exactly what it claims. The two that I used both fit properly and improved the fit of the rings that I used them on. They are almost invisible in use. The cost seems kind of high even if I used every single one in the bag, but if I consider that it made two rings wearable that hadn't really been wearable before, then the expense seems a bit more reasonable and certainly easier and cheaper than having rings resized by a jeweler.

Works great!
Perfect solution to tightening my engagement ring. I know I should just have it resized but it’s winter in Chicago and if I resize then it might not fit during summertime when my hands swell from the heat. For now, this is the best and easiest fix. My ring fits perfectly around my finger now and hasn’t been sliding from side to side.

Falls off, not for small fingers
If you wear a small ring size beware. This falls off extremely easily. You have to heat it up to mold it to your ring well but it's not a great solution. Nice and smooth though doesn't hurt your finger. Comes with every size but smaller fingers are harder

Après avoir essayer plusieurs, je confirme que ces réducteurs sont parfaits. Ils se clipsent et s'ajustent à votre anneau. Assez discrets par rapport aux autres Je recommande même pour ceux qui ont des petits doigts

Very Useful

They’re working precisely as I hoped they would. I’ve even added them to other rings that fitted fine but the adjusters have made them fit even firmer so that they don’t move at all whilst still feeling completely comfortable.
