My last one started failing in one year
I like this machine because it's a solid white noise and I don't get distracted by the clicking of a loop sound. But looking at my order history I see I ordered one in February 2010 and had to replace it by January 2014.  Now that version is making a rattling noise and is getting quieter so I check to see when I ordered the last one and it didn't even last year at the same level of noise.  plus the rattle is annoying.  $44.00 is too much to every for a piece of equipment that should last a lot longer.
