Query: Excellent product!

This little machine is a God's send. It does an incredible job of masking the TV noise which emanates from the next room with which it shares a wall. I can watch movies and actually hear the dialog as opposed to just looking in order not to disturb my husband who goes to bed early. I can sleep late if I want to and not hear anything going on around us - it is a blessing. My only complaint is - why did i wait so long to get it!
