Beats electronic white-noise makers hands down.
I've had the Marpac single speed for nearly three years now. It gets used daily unless the A/C is running. A nice feature is the ability to change the tone of the sound by adjusting the vents on the top and side to get a higher or lower pitch according to your taste. It's deffinately much better than the awful sounding electronic noise makers that I've tried.<br /><br />The only minor issue I've had with it is recently it developed a slight rattling noise. The fan blades inside had become coated with dust causing the fan to be unbalanced. This was not a fault of the unit, all fans will collect dust. The top came off easily by removing four screws from the bottom. After cleaning the dust off it works as good as new again.
