@annya Yes. There were 3 different versions at the conference, one of which (afflovest?) had a compressor built-in. I actually tried the Smartvest at the support group meeting a few days ago which was provided by the sales rep. I am not sure that it does anything for me although it works for a lot of folks. I don't think the doctors at the conference were saying not to use them -- on the contrary. Just that there was very little data to support their effectiveness. They also do not recommend any particular one over the other, except to experiment and see what works for you. I find the nebulizer and 7% works quite well for me provided there is mucus -- I suspect I have very little. The Aerobika doesn't really do much for me either. Interestingly, one of the participants in the support group said her pulmonologist at National Jewish told her she did not really need the vest since she is so active. I feel that if you know you have mucus and has trouble getting it out and have not tried the vest -- it is worth investigating and trying it out. --Mary
