I have been using the SmartVest (air compressor type) for about a year. I got a pulmonologist order for it and my insurance is paying most of it. I make a small monthly copay. The compressor is heavy but it comes in a case on wheels (like a carry on piece of luggage). I use it for 15 to 20+ minutes 1 time a day when after I do the levalbuterol and saline. It does help with getting some of the DEEP mucus up. I can sometimes tell that I can take a deeper breath after using it.
I would not have it, if insurance was not paying for it. It cost as much as my used car!!!

Can someone post the link with pictures of the Afflovest?
