The device works well, unfortunately there is a small detail: the tank containing the liquid product spray breaks after thirty uses! Replacement cost 26.69! I note that the fragility of this piece is obviously intentional. The calculation is finely executed: one is forced to buy a kit containing: a mouthpiece, nasal, mask for adults and another for children, a nebulizer with compressed air hose and extra long 10 filters. Parts whose obsolescence has not been programmed and that actually wear is almost not only the tank whose manufacture clearly does not cost 10 cents is fragile. My advice: try to make the part by a handyman. I do not know if it's smart to do it commercially, good: they have probably studied the issue
