Product review (4 stars): great cooler if you do it right
this cooler will cool if you pull the temp control knob off and turn the set screw located on the left side clockwise(to the right).you may have to adjust it several times to get the right setting.remember to put a thermometer insde to check temp.i adjusted mine after not being able to get it below 46 degs and now it stays between 32 and 38.once I had it set I fine tuned it with the control knob.problem solved
