Roasted feet, High current draw.
They work as stated.  However there are a few issues.  First off there doesn't seem to be any temperature regulator in these things.  They get uncomfortably warm after about 20 or 30 min. The description says 152 deg, and they are not kidding.  The heating unit is a 7 in long by one inch wide strip that inserts in a zipper at the toe. It slips between the insole and out-sole of the slipper.  you have to make sure it runs right down the middle or it will only warm one side or the other on your foot.  The &#34;Y&#34; cable is kind of short so what ever your connecting it to has to be right next to your feet. and the &#34;Y&#34; itself is very short and limits how you can move your feet.<br /><br />You can't just use any USB adapter.  It draws so much current it got my IPad charger so warm it smelled like burning plastic and was very hot to the touch.  They say you can plug it into a computer, but I would be afraid it would burn something out.  It would definitely drain your laptop battery,<br /><br />I will say it will get your feet warm after an evening of shoveling snow.  So if you have VERY cold feet, this is what you need.  Just don't fall asleep with them on.
