What are the pitfalls of a Duracraft humidifier?

Duracraft Cool Moisture humidifiers are loud, especially on the high setting, and the tanks are small, according to reviews on Amazon.com. Duracraft Cool Moisture humidifiers do not work well in large rooms and have to be refilled on a regular basis when used on the high speed setting.

Duracraft Warm Mist humidifiers are not as loud as the Cool Moisture humidifiers, but have the same issue of a small tank size. The tank must be refilled every seven hours when the humidifier runs on the high speed setting. Reviews on Amazon.com suggest that the Duracraft Warm Mist humidifier does not work well in large rooms.
