We received this just in time.  The whole crew came down with a sinus cold.  This cool mister really came in handy at night when things really start to dry up! It really easy to use.  It has an easy top fill and there’s no filter to clean.  It’s light and the perfect size to move from toom to room.  The best part is the essential oil tray!  The auto shut off feature allows you to freshen up your room without worry!
