Not cordless.  Not warm enough.  Most disappointing purchase of the year.
I bought this because I thought it was a cordless heating pad (like you charge it up and then unplug it and use it).  Not only does it require to be plugged into the wall to work - it doesn't even come with the cord.  And when it does work, it barely gets warm at all.  This is the most disappointing buy of the year for me.
