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.

Brilliant Item.
I liked at how simple they are to use and my rings stay in place. Highly recommend them.

Great quick-fix.
Nice little box of sizers for common ring widths. Very comfortable and near-invisible when in place. However, since they don't wrap around the ring, they can pop out easily when removing your ring. And then they're hard to find on the floor since they're transparent... All in all, good to have for those rings that are too big and you don't want to (or can't) resize at the jewelers.

JUST AWFUL! EDIT
So fiddly, does not "operate" as easily as shown on the video. Wasted money as I cannot be bothered to return it. Don't waste your time or money These arrived on 11 March, by today 15 Mar, the sizer came off, simply disappeared, so I am trying yet another one... seriously disappointed!

It worked
I used this on a my wedding band that had got so loose it kept slipping off my finger and I was afraid I would lose it. From within the packet of assorted sizes I chose the size that fitted my ring. I followed the fitting instructions and threaded the retaining strap through the slot and pulled it up tight. That’s where I encountered a problem. I pulled the retaining strap through the slot to tighten it against the ring and I run out of retaining ridges. The ridges didn’t go far enough around the strap, so when it was cut to length (it works on the principle of a zip tie) there was nothing to hold it in place. Luckily I got over this by cutting the retaining strap off completely and pushed the U section silicon spacer part onto my ring and slid the ring and spacer onto my finger. It now fits my finger perfectly and because the ring fits inside the spacer U section so it doesn’t slide out from under my ring. Dropped a star for the retaining band issue. Update: Silicon spacer went black after a few weeks of continuous use and began irritating my skin under the ring, had to take it off in the end. One of those things that sounds like a good idea, but doesn’t work out in the end.

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.
H**!
Does the job well!
I found the adjuster easy to fit. The instructions were pretty clear. After attaching the adjuster to my ring, I trimmed each end, in small increments, until the ring fitted my finger perfectly. At first it felt a bit odd, but after a short while, it feels fine. The adjuster is invisible on the face of the ring and is pretty inconspicuous against the palm of my hand-will definitely use again and I would recommend.

Will be buying more
I don't review very often. But these are amazing I can wear my wedding rings again. Tried lots of rings sizes which were uncomfortable of fell off. I don't know I've got this one, I've cut it to size. Will be buying more! They have saved me getting all my wedding rings re sizes

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.

Mein Verlobungsring ist leider auch nach Verkleinerung durch den Juwelier zu groß gewesen, deshalb habe ich mir diese Ringverkleinerungen gekauft. Sie funktionieren einwandfrei. Es sind sowohl diese Einlagen für verschiedene Ringbreiten, als auch die Spiralen im Preis enthalten. Die Spiralen kann man dann selbst so zurechtschneiden, wie man es braucht. Simpel und funktionstüchtig. Sitzt gut, drückt nicht und fällt nicht ab :) Mir ist nur aufgefallen, dass sich das Material nach langem tragen leicht gelblich verfärbt. Stört mich persönlich aber nicht.
