When i was in the hospital they gave me an acapella ( the green one) to use till they got me the vest. I myself dont find it effective at all. But i love my flutter <img src="i/expressions/face-icon-small-happy.gif" border="0">
The flutter seems to be way more effective than the acapella. I like the vest ( i used to hate it) but it allows me to be hands free to type on here and other sites ( I am using the vest right now). I usually use the flutter at night or whenever i feel some crud needs to be moved out. I am guessing ( although it isnt good advice) that as long as you are doing some kind of clearance ,it is better than doing no clearance technique at all.
