After first use my INQUA device appears at least as good as the Pari Boy. The volume is comparable to the Pari Boy. This "noise" but is expected to be to prevent in such a relatively small compressor equipment barely. The handling inclusive cleaning is absolutely identical to the Pari Boy. And the nebulization inhalation solution also works perfectly.
But much better than the Pari Boy is 1. the ability to store all accessories in the integrated storage compartment, 2. the well dissolved cord storage at the bottom of the device and 3. the vernĂ¼ntige handle. All of these "features" did not exist at the Pari Boy 2. And the budget compared to the Pari Boy Price is undoubtedly an additional, not inconsiderable advantage.
In summary, I am with the INQUA inhaler been extremely satisfied. Therefore, there's 5 star and a clear buy recommendation.
