Well they work great for teething babys, I know this! However I never got to use these particular ones, I put them in my baby bottle steamer (where I sanitize all bottles, binkies, TEETHING TOYS, & breast pump parts) & the keys melted! Literally melted! I've NEVER had this happen b4, maybe it's because of whatever kind of gel they have in them? That being said I have a fussy teething baby so I've already ordered a replacement! Just DO NOT STEAM STERILIZE!!!
