I have used these sound machines for 3 years now. Each bedroom has one and I always take one on vacation. I buy the single speed as it has the faster speed and it's the only speed I use - it's slightly louder than the slower speed. This helps both myself and the kids sleep better, and helps to mask some of the outside noise that can come from living on a busy street.
