This unit is completely reliant on your room temperature to maintain a desired temperature. Kinda defeats the purpose doesnt it?? when it was hot out, the unit could not get below 62 degrees and when it was cold it would stay below 48 degrees. completely messed with our wines. the best part is after 8 months it was probably too stressed and decided to stop working altogether. neither side would generate any cooling. utter junk better suited for the scrapyard.
