It is lightweight, quiet, and easy to use. Following faithfully the instructions for use and maintenance, it is a medical device that lasts for a long period of time.

It broke on the 5th application. I contacted the company Aeolos and they said it's the chip's fault. It's not covered by warranty because it has to do with usage... the medication shouldn't stay on it after use at all... if you don't wash it immediately, it breaks...
I paid another 15€ for another chip... they say it lasts for 6 months... on the 10th application, after a good cleaning, it broke again...

Having used other nebulizers, this one is 10 times better, faster, and adjustable according to the patient's breathing. The only downside is that the filter requires infinite attention because if you touch it with a cloth, it breaks.
