I can sleep again !
After using one of these to drown out husband's snoring, I can't sleep without "white" noise. The one I had for 20 years was a 2 speed and when it quit working I went searching for a replacement. There is not a machine out there that provides the consistent "white" ,static free noise this machine does. I purchased the one speed after reading the single speed provides the same noise as the high setting on the 2 speed model. It does, and costs less ! You can adjust the noise by turning the top and or side which closes holes, and softens the sound if it's too loud. Amazon was the best place to buy ,quick shipping as always. I expect to get 20 years service out of this Marpac machine as well. Very happy with my choice of the one speed Marpac!
