Query: Works great for my kids

This white noise machine was the best thing that happened to our house! I used to run fans in my kids' rooms to drown out noise and help them sleep, but their rooms would get too cold in the winter. I looked all over for a noise machine that sounded just like a fan and came acroos this one and we LOVE it! I have bought 3 of them (for each of my kids' rooms) and we all sleep better. It is so compact that we even take it on vacation with us. I would recommend the Marpac 580a for anyone with young kids who wishes for more sleep!
