I'm currently on my second set of these, finally lost the last one of the trio recently after over a year of wearing them everyday at work. Really, I'm still hoping to find them, they held up so much better than my other silicone rings had, as well as being shiny and pretty.There's no cons to be seen unless you don't like a slight swirl pattern in the rings from being poured into the molds, which I personally find gorgeous. They're incredibly comfy, enough I forget I'm wearing them. I don't think they look like real metal, but people have been shocked when I've taken off and squished the silver and gold ones more than once.I hope they come out with bigger packs/all gold ones someday!
