Excellent compared to machine bought at local medical supply store. I wasted 60 dollars on overheating machine from another company. My last Medline machine lasted many years with no problems.
It is having great quality and working good.
The Peri adult nebulizer compressor with kit are a game changer from my other brand. Connections are smartly designed, ergonomic, tight fit and made for long term use. Because of this, your breathing medicine gets deeper in lungs. Very happy with my purchase and definitely recommend.
