a great buy
We purchased this product because our daughter's room faces a busy street, and early morning garbage trucks, buses and motorcycles would wake her up.  She has slept wonderfully since we got the sound machine.  It is as simple as can be - plug it in and flip the switch.  We've had it for about 2 months, and couldn't be happier with it.  By the way, we can still easily hear when she wakes up through her monitor, so no worries with that.
