I purchased a set of the work safe silicone rings and they’re very nice. I was a bit bothered by the ‘hers and his’ sets - this does not leave much room or accommodate a ‘hers and hers’ or a ‘his and his’ as they are locked into set sizes. In addition to that after wearing mine for around a week (following the included guidelines around taking it off to sleep etc.) I have developed a rash around my finger which potentially indicates the presence of some kind of irritant. Otherwise they look good and feel fine to wear though as indicated I will not be wearing mine anymore going forward.
