Looks, perceived to the touch well. Quality goods. Works as stated-just turns water into steam. The instructions say that "clean water" is not suitable, only "tap" or mineral. I do not know what to think, because Mineral by definition with high content of salts, and for humidifiers recommend the opposite almost distilled. I poured the usual tap and put it near the laptop, let's see. In the car in winter, I think it makes no sense even to try.
