I have had my Afflovest for over a year now, and really like it much better than the InCourage best I had before. Not tied to a heavy compressor, much easier to travel with, you can move around with it if you wish although I usually do nebulizer at the same time. Seems to do a better job on clearance too. Often I have to get on a slant pillow while using it to help with drainage. This is easier when you are free to move around. It does weigh about 10 lbs.
