@turnbacktheclock I actually use my Pari Trek S more than I use the Pro Nebu when I'm home. I take the Pro Nebu if I'm going on a trip because it's smaller. But like others I'm still waiting on the Innospire Go. I've never seen any nebulizer work as fast as that one. But the Pro Nebu is ok. I think I actually bought two of them because the price was so good but it was awhile back so I don't remember what it was. Oh, now I'm remembering why I went back to my Pari Trek S at home because I can use a mask to nebulize and then be hands free because I work at my computer while I'm on it. With the handhelds you can't really do that as well. Nan
