I bought this less than a month ago, and the first 2 uses...fantastic!  3rd use, it jams twice.  Smelled burned metal, and it took a bit to get lid off.  Gear on paddle and on plastic lid dark.  Paddle got stuck even after letting ice cream thaw a bit before attempt.  The bad part is, I can't get a replacement blade or lid.  Out of stock.  Does this happen alot?  Internet says yes.
