Got this because I can't sleep in a completely quite room.  Usually I run a fan but the temperature doesn't always allow me to do that.  This is a huge help. It's the perfect size and portable.   Can be used al night or has a timer.  My favorite sound is definitely the rain, but they all sound awesome.  And can be used with batteries or the power supply  so perfect for camping.  My son loved it so much I bought him one for his room for Christmas. And itsnot an eye sore. Small and sleek. [This review was collected as part of a promotion.]
