Review on BougeRV 42 Quart Insulated Protective Cover, 12 Volt Portable Refrigerator Cover, Car Freezer Cover (Refrigerator NOT Included) by Justin Spence

Using it in Semi.worksamazing when it works. Currently it is set at negative temperature and won't get below 40. 3 different occasions in 2 weeks that my food becomes unfrozen. So now I have zero food to eat. I was using the power plug to my inverter but that kept getting faults or maybe faulty adapter. Been using the cigarret plug and seems to work nicely. But I woke up one morning to my inside temperature at 34 degrees and food unfrozen. Currently reads 01 degrees but my thermometer reads 50 inside. I believe I have a faulty thermometer on the BOUGERV cooler, why else is it reading below freezing but the cooler isn't freezing. If it worked all the time I would absolutely love this thing. But now I'm stuck with melted ice cream.thawed out food, and will be hungry until I can finally get home. I feel like I got ripped off, sent a faulty unit and hope to find a better one soon. Or maybe the seller can help me out and bypass my issues. I LOVE THIS THING WHEN IT WORKS
