Great Sound Machine!
I love this thing.  I purchased it for my 2 year old son who was having trouble taking decent naps & sleeping through the night and it works wonderfully.  His bedroom is very close to the living room and any noise would wake him up.  With this sound machine he takes good naps and has been good about sleeping at night.  We also have an 8 week old baby who seems to sleep a lot better with it as well, so I will be purchasing a second machine.
