I love the idea of this teether . unfortunately , I be not sure if I should we it . I just get my order from UPS . I sterilize the Raz accord to the instruction on the package . I put it in boil water for 5 minute . cool and inspect . the glue or adhesive that hold the ring part to the raz part melt away and the ring part be break off . very upset . I would have sanitize in the dishwasher , but I be in a hurry to give to my baby . a flimsy product .
