Title: Worth the money
Review: We've been sleeping with sound machines for years, falling asleep to the white noise. I bought two of these for my two girls and they perform as advertised. They've used them for over a month now with little complaint. My older daughter says that hers has a repeating pattern that she picks up on sometimes. I think all of the electronic ones do if you listen for them and try to pick a sound pattern out. The only way to avoid that is to buy one of the $50+ mechanical sound machines which can also have problems as they are prone to sucking in dirt and hair.
