It does the job. Wish it had some more programmability, but it is a lower priced product. It pushes out humidity well and it raises my basement room, that is 10x12 and sits at about 30% naturally, up to about 60% when going at its max level. Water supply lasts about 2 days. Item comes in two parts. The tank at the bottom, and the humidifier at the top. You could attach to a different tank without difficulty if you wanted to.
