Ask Silentalero. He's about the only one, outside the commercials, praise it.
Me personally, I've never used or tried it. I don't think it would do much. I mean your stickin' an obstruction in your airway and if it is that good, why didn't the manufacturer make/install it on their own? I mean if it works as advertised, it's an inexpensive item to improve performance and efficiency.
