This noise machine didn't last two nights in my room before our little guy snagged it for his bedside table! He just started sleeping in his own room and this, and his nightlight, work wonders to make him feel secure. There are lots of different sounds...he loves both wind chimes the most, and goes back and forth between the two. I really like that it helps him sleep. The machine is compact, travels easily, and has easy to use buttons. It also has a timer so it doesn't run all night. The only con for me is that some of the sounds are a bit tinny and there's static where there shouldn't be. Otherwise this is a great little unit and works really well for us!
