Product review (1 stars): ** DO NOT BUY**
Purchased the unit in Nov 2013 and had no issues for 6 months.  In June 2014 the unit couldn't keep the temperature that it was set to.  The unit was set to 55 degrees but displayed 65, I then set the unit to 45 degrees and no change.  I've had 25 correspondences with the seller (AKDY) between June and Aug. 15 and the situation still isn't resolved (waiting over 2 weeks in some cases to get a response).  I finally had to ask Amazon for AKDY's customer service number.  When I called, AKDY accepted zero responsibility.  When I pressed the issue, AKDY's customer service rep hung up on me.

Highly recommend - do not purchase this item or any item sold by AKDY
