Brilliant item, didn't affect the look of the ring
I bought this to adjust a resin ring I'd had made with my late mums hair in it. When the ring arrived it was beautiful but far too big so I ordered this item. I was worried I'd lose the hair under the spiral/twisty adjusters so I used the spacer things in the pack instead. Took 5 minutes to work out how to do it and assemble it and now the ring fits perfectly with no impact on the visual effect of the ring. I'm actually surprised how pleased I am with the whole thing, I'd definitely recommend this to anyone looking to adjust a ring.

Useful for what I need it for, but one small complaint
I recently got married. My wedding ring fits well but in the cold my fingers are a lot thinner and the ring moves over my knuckle a lot more easily. So, I got this ring adjuster to prevent it falling off by accident. I knew it was going to work because with the adjuster fitted onto the ring, I cannot fit it over my knuckle. I have to put the ring on and then slip the adjuster into the gap between my ring and my finger. Once fitted, my ring does not budge at all unless I intentionally move it. I don't notice the adjuster is there. The only time the adjuster lets me down is when I come to wash my hands. It is prone to slipping out from under the ring when soap is around it. It hasn't been a major issue but I am slightly concerned that the adjuster (or the ring) may slip off by accident and end up going down the plug hole. This concern is pretty remote, as I notice the adjuster coming off right away. However, I don't underestimate my capacity to be clumsy.

Use the coil
Ring adjusters Needed my ring made smaller after losing weight (but Mounjaro can also have the opposite effect on other kinds of rings !) I was pleased that this product came with two types of adjuster I tried the curved insert supplied with double sided tape and it only lasted one day before it disappeared - probably down the shower drain Plan B was to try the coiled insert option which at first sight feels a lot more secure………with the added bonuses that 1.if the ring becomes difficult to remove, the coiled insert can easily be unwound 2. if one if these does go down the drain, the generous length of coil supplied means new inserts can be re-cut many times over So it appears to be s very cost effective product well worth 5 stars

It's a temporary fix
I was quoted £98 to get a ring resized to a size smaller. I bought these instead, thinking £7 is better than £98 and worth a shot. The instructions were really confusing and the plastic bits aren't sized very well. It could do with an instructional video tbf. After finding a plastic insert that just about fit, I then found it made the ring too small. So I tried the springs. Again no clue as to sizes but I figured as I didn't need it sizing down too much, I would go for the smallest. I wound it tight around the back of the ring, tried it on and it does now fit comfortably. I don't know how long the springs will stay in place for. There is spare if they come loose, but I guess you have to accept that this is only a temporary fix. These things won't last forever.

Does the job!
Although it might seem a bit unneccessary to buy several different sizes at once, I found that I needed to use different thicknesses for different rings, so it was not a waste of money (and anyway, this was not an expensive item!). There is plenty of length for each size, so if one size does fit all your rings, no problem. It is very easy to cut with household scissors and you only need about a centimetre per ring (obviously maybe more if the ring is very loose). Overall, very pleased with this product and it has saved us a fortune getting rings re-sized by a jeweller!

A good idea but ...!
These looked good in the picture and just what I needed, but with no instructions and not self-evident how to fit them, I can’t attach them to my rings which makes them pretty useless! - A waste of money, but fortunately not a lot of money!

Easy to use and comfortable ring adjusters. Good choice of sizes
These feel more comfortable than the old plastic barrel shape adjuster. Easy to twist onto the ring. A good choice of thicknesses too. They slip round when washing up or using hand cream but once dry they’re fine.

Would not order them again
Ordered this item due to me losing a lot of weight my rings are just spinning around on my finger Added this item to my rings they were still moving about quite a lot and very irritable I found so I remove them on the same day
