Purchased 1 year ago. My child used it a few times. I was relieved when my child stopped using a pacifier with this product, but they started again six months later. They are much more aware now and strongly dislike it, so I can no longer use it. If it goes well, I think they will be able to quit in just 1-2 tries. I hope it will be useful for the next person. Price non-negotiable.
