Awesome Machine!
I have used a white noise machine for the past 15 years to help me sleep.  My old one broke last year and I did a lot of research to see what machine I should buy.  I was going to go with the usual Sharper Image model when I found the reviews for this machine.  Everyone said spend the extra money, you'll be glad you did.  Wow they were SO RIGHT.  This machine is just fantastic.  It's very simple, basically just an on/off switch and some slight variations in volume but not much.  It doesn't go super super loud but it's loud enough for me.  I have been sleeping so well!  So very happy with this machine.
