Review on Ringo Invisible Ring Size Adjuster - Multi 10-Pack for Loose Rings by Nicole Mcleod

I was skeptical about buying these after reading some bad reviews but I am glad i did it. This band works great to keep my soldered wedding/engagement ring from falling off my finger. It took a bit of trial and error to get the ring size right, but once I did it I bent it slightly and it easily slipped right under my ring. Be sure to wear the ring while the ring is on your finger. Also, it doesn't slip. Maybe try a smaller or larger strap until you find one that fits your finger snugly. The strap is comfortable and doesn't over tighten my ring like I feared. Small protrusions on the strap do not stick to anything. It's also easy to remove and reposition. I would definitely recommend them for big band rings. I don't think they will work for a thin band ring.
