For me, I chose the Innospire Go for 4 reasons:
I was nebbing 2-3 solutions 2-3 times a day, and travelling 6-7 month of the year. Speed, portability & battery length were of paramount importance to me. My daughter, 40yo with SEVERE lifelong asthma, mild bronchiectasis & post-Covid lung issues has used about 5 different mech nebulizers, and this one, in spite of its shortcomings, was the only one she recommended.
It was okayed by my pulmonologist should I need to use inhaled Tobramycin or Arikayce again (likely.)
I was able to afford the $250 due to a few dollars in my health incentive account that made it affordable.

I now have recovered to the point that I need to neb less, but I still appreciate being able to do it easily, anyplace & anytime. And it is reliable - I know when the head begins to leak, I have about a month to replace it. So I am able to always have it available.

If I was stationery & didn't care about the noise & speed of nebbing, I would not have spent the money, but it absolutely suits my life at this point.
