Nice implementation of a simple effective solution to the problem. Lots of sizes were included making it a very good value! Requires a bit of effort to install, but results are worth the effort.

Made well, however if your ring has a rounded interior wall, the unit will require adhesive. The adhesive that comes with the product works well, but it is not easy to get the double sided backing off the adhesive.

After loosing some weight, I struggle to keep my wedding band on. Its been resized, up and down before so I would prefer to get to a stable point before altering it again. I have been looking for a solution... the previous one is plastic as well and clips to the band. works great until the plastic wears creating a sharp barb that pokes you and snags on just about any fabric. Next up is this product, the Invisible ring size adjuster.... fit the band well and if your band is wide, they have you covered. In my case however, there is NO retention feature on these save two flanges to fit on either side of your ring band. As soon as my ring moved... the plastic fell out. For me... these just won't work.

Nice concept but does not stay on the ring at all.

I wear the Ring Conn 2 sensor ring in a size 6 on my pinky. It was a bit loose (it came off once while doing laundry, and luckily I found it!). I was having trouble trying to figure out how to make it a better fit since the sensors are on the inside bottom of the ring. I was going to buy the glue adhesive, but I didn’t want to take a chance that it would ruin the ring. This set of ring sizers was perfect. Although I only needed 1 specific size, I placed it inside the top inner ring and snapped it in perfectly. It is now snug yet easy to take off, doesn’t ruin the appearance as it is clear, and allows the sensors to work accurately. I highly recommend this ring sizing set.

Only complaint is that they should include more smaller sizes. They come loose after awhile. Otherwise they are very good.

Does not stay on my ring. Falls off when I put the ring on, I have to then adjust it back to the right spot, then it is fine for a while until I get my hands wet or adjust the ring at all. Would not purchase again.
