Received this as a gift, was very excited to try the sous vide feature.  What a letdown!  Attempted to make the maple glazed carrots, preheated for over 1 1/2 hours, (even added more boiling water) and still could never get the water above 152°.  Useless.  As a regular crock pot works about as well as most of them, just don't get excited about the sous vide.
