It worked for 3 days.   I did my research and spent the extra money for one that is supposed to work.  The first three days it worked great, temp was set to 44 degrees and then it went to the 70's.  I can't return it because I bought it while my house was being renovated and it wasn't installed for two months after receiving.  I built an island around the specific dimension of this cooler.  What a waste of money!
