I bought this several months ago.  I was a bit concerned because some reviews said it 
moved around off the bed".  It does shift some...but no big deal.  Simply pull it back up around you.  The benefits FAR outweigh this shifting issue.  It is the softest blanket I have ever had.  It is just lush!  The electric blanket part allows for a mild warm, up to as warm as you would want it to be.  I have washed it (following directions given on the bottom of the blanket), and it turned out as soft and beautiful as before.  I am a very picky shopper.  I LOVE this electric blanket and would highly recommend it to anyone.
