Little update, I found the e rapid to turn off so quickly today that I questioned what was still left in the cup. When I looked there seemed to be a lot, so I tipped the cup forward to allow the saline to flow into the component to touch the head. I was then able turn it back on and nebulize for several more minutes with the mouth piece, pointed slightly downward. I wonder if I had been nebulizing with it perhaps tipped upward a bit, perhaps preventing the fluid from hitting the head (which is what makes it think the session is over). Anyone else have this experience?
