Maybe you can return it? I looked up the price $1000 - wow.

FWIW I've been happy with the eRapid/eFlow by Pari. It's been around for a while and over time has been price reduced. With an extra discount during a special it was around $600. Still pricey, I know, but for something I need to work and rely on it was worth it. Very light, very portable. Runs on batteries or plug in. It leaves behind 1mL of solution and there is loss while nebbing, unlike aeroeclipse. Definitely a trade off but it has its place in my arsenal. I use the Pari eFlow when traveling, when time is running short, or if I need an extra neb from time to time.

I believe some of the MAC or pseudo inhaled drugs require it. Drugs companies have rebranded it to use with their pharmaceutical and sometimes provide nebulizer and drug together.
