New here with BE but in the category of learning how to avoid NTM. Upped my game and purchased what you did, the Ombra, AeroEclipse XL and Aerobika. 7% saline is the only thing I neb. Time consuming, plus cleaning & sterilizing. Clearance perhaps a bit better than Innospire Go but jury still out.

Philips stopped making the Innospire Go. People returned them for replacement because they stopped working. The fix for non-working device is easy. Wipe the gold contacts with an alcohol pad (on the handheld piece) and it'll keep working. That doesn't solve the replace the head every year advice, though.

Pari makes a portable called Velox, available in Europe only. Maybe available in US in awhile as there is a market need but no plans now. Pari also makes eFlow. Looks amazing and gets great reviews by users. Last time I looked it was $800+. Gulp. If the cleaning is straight forward I might spring for it.
