This thing is great!
I've had this for over six months and I use this device every night, and take it with me when I travel.  I hate HVAC units in hotel rooms that won't let me leave the fan running all the time, but with this thing on, it doesn't matter.  It uses the higher of the two speeds that the other unit offers, and that's fine with me.  Well worth the money.
