I'm using the Hillrom Baxter vest. I've only been using it for a few weeks as it was just prescribed by my pulmo. It has a compressor and it comes with a case on wheels like a small suitcase if you need to take it traveling. I'm not sure it's doing much at this point, but I haven't used it long enough to make a firm judgement. I also recently switched my neb solution to 7% from 3%. That's where I noticed the biggest difference. The 7% really helps me bring up stuff that wasn't coming up before. I'm currently doing the vest after the nebbing but I may switch around. Anyone else have any input on vest before or after nebbing?
