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.

Great ring adjusters
This ring adjuster works perfectly. With the assorted sizes they fit rings from thin to wide. I had lost weight, and I was afraid my wedding rings would slide off my finger unnoticed and be lost forever. The ring guard can't be seen or felt while wearing. It really solved my problem and was much, much cheaper than having my rings resized at the jewelers.

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

Really great!
Really great value. It comes with several sizes to choose from. I have a very slender band and the smallest siz worked perfect. I have lost weight and already resized my ring once. This is a great product to use intermittently so I don’t have to get the ring sided multiple times. It is easy to put on. You can not see it at all. The only down fall is if you use lotion it will get caught in the grooves. It stays in place and does not slip off. Overall really great purchase for the money.

Works well & keeps ring from spinning around
These turned out to work well. Unfortunately though, my ring was still too big with this sizer on. (No fault of the products.) I just lost a lot of weight & my jewelry store closed the closest location to me. So now I have to drive 2 hours one way to go drop my ring off to get resized. Until then, this sizer will have to do the job. I would recommend this product.

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.
