Hi, Just to inform you I have recieved two of these masks given to me by my line manager for Portage Home Visits as a trial , but didnt find wearing it very sucessfull , they did not fit snugly to my face and the foam strip had melted off the clear plastic during both visits so not very sucesfull for me and they are quite expensive .I have returned to wearing the original standard mask but as we all know the child cannot watch as we make mouth sounds with these.
