I love, love, love this machine.  It’s small enough so it doesn’t take up a bunch of room on the nightstand.  It has six different sounds.  Ocean, White Noise, Rain, Brook, Summer Night and Thunder.  My favorite is Ocean.  It also has a timer on it, so you can set it for 15, 30 or 60 minutes, so it will automatically turn off. I leave mine on all night.  The sound is so soothing. It really helps me get to sleep!  Great product!! [This review was collected as part of a promotion.]
