Perfect for people who need CONSISTENT sounding white noise to sleep!
So far so good with this!  We were not sure about spending the extra money over other models but we made the right choice here.  Have been using for one month every night.  Cord is plenty long enough.  Continuous sound of a fan!  No looping or changes to the sound.  Tone is mildly adjustable by turning the outside piece of the unit.  Volume is not adjustable, but placing it farther away from you would make it quieter.  Simple easy to use.  Switch it on and off with one switch.  We love this and would not sleep without it.<br />UPDATE: Three months now still worth every penny!! Can be heard over the small fan we run at night in our room.  This is great because the Dohm drowns out any inconsistencies in the actual fans noise.
