Pros: Compactness, convenience, work (it blows the lungs well, the pressure is good). There is something to compare. With its cons: Not a very good mask. Condensation accumulates, does not have time to disappear. As a result, all my mustaches are in saline (this was not the case with another Japanese nebulizer).
