Good results for me.....
I am not a great sleeper, one of those who tends to wake up easily when noise enters the room - a cat scratching on the door, one of the kids running up the steps, birds chirping at 5 AM in the summer when the windows are open.  If I have been asleep for more than 4-6 hours, I will end up not being able to get back to sleep.  I LOVE to run a box fan as I noticed that I sleep better with the noise and the gentle breeze.  But while researching white noise as a possible sleep aid I came to realize that is is likely not the breeze that I was enjoying, but the white noise created by the fan.  So in the endless quest for good nights' sleep, I decided to order this Dohm machine and see how it went.  I've been using it for several weeks now and, although it is very hard to quantify the benefit, I am convinced the machine is helping me sleep better.  It creates a nice noise zone which normal small household sounds cannot penetrate.  If you enjoy sleeping with a fan on, or other consistent background noise, I encourage you to give one of these a try.  I gave it 5 starts for the simple reason that ANYTHING that helps me sleep better, longer or deeper gets a top rating.  And I believe this is working well for me.
