Have to agree with Andre. 12v Fridge on Raven is 20 years old and still going strong. We also have a 20 year old engine driven eutectic that is out of action but only because of a cracked holding plate.
I'd be asking the Vitrifigo people why their product is utter garbage and if they can give you any good reason why you would buy another , which as Andre mentions, is likely to only last another eight years.
