I used Pari Boy Go this evening. It is almost as good as Pari eRapid I have. Pari Boy Go took 3min 30 seconds for Duoneb and 6 Minutes for 7% Sodium Chloride. It loosened Sputum like pari eRapid but I produced slightly less sputum than eRapid. I always felt eRapid works to loosen sputum in upper bronchus and Pari Pro Neb Max reachehes down further to alveoli. I use Hillrom vest while I nebulize Sodium Chloride with my Respiratory Tech's advice and it works better for me when I combine it together. Pari Boy Go has USB C port, but cable is not included in the package. Cleaning is really simple. It only has 2 pieces to assemble & disassemble to wash which means less chance to contaminate from handling. I recommend it to use it for Travel. Even though I don't know the longevity of this machine.
