Passy-muir products are fantastic! I have been using their speaking valve for a while now and it has made a tremendous difference in my ability to communicate effectively. The Passy-muir website is great too, providing ample information about their products and how to use them. I highly recommend Passy-muir to anyone in need of a speaking valve that works flawlessly.
