I love it, beautiful * I recommend using 5 v charger (not included). Do not use fast mobile charging chargers because you need to always be plugged in and that can make the life of the product is shortened. * Do not use oils: it can clog the duct and make it burn (i use it with some body spray 100% of alcohol). * The capacity is of a normal glass of water, when the water runs out automatically or at 20 minutes of use. * Operation: leave pulsed to turn on, click again if you want to leave a fixed color light. Press once to start steam.
