I've had my Red Rooster sound machine for several days now. It's a very nice,lightweight which would be nice for traveling. I especially like you can use the power cord or 3 AA  batteries. That is awesome for when you lose the power. I don't like complete silence I have to have a little noise. I have tinnitus so the ringing in my ears is really noticeable with no noise. I also like you can set the timer on it for 15,30 or 60 minutes. I'm very satisfied with it. [This review was collected as part of a promotion.]
