This is the 3rd of these we have purchased over the past 10 years.  We had tried other sound machines, but were not impressed.  My dad had one of these that he has used for years and years and they knew I was looking for one, so they gave us one as a baby gift.  By the time baby had moved out of our room, I was hooked, so I needed a 2nd one for our room.  Recently, my 13 year old was having trouble getting to sleep a little too often and was also often sleeping restlessly.  I had a thought to let him try our noise machine one night when he was having trouble getting to sleep - Eureka!  Next day I had another one heading to our house from amazon.  We may end up with another for my other son and therefore have one for every bedroom.  I really love it and even pack it with us whenever we travel.  We have both the single and double speed.  We like both, but this one is loud enough for me and is adjustable to both quieter and louder by turning the holes on the side or the top.
