Query: Product failed after 1 week of use

I purchased the Vector run a 4-amp max rated thermoelectric cooler, and it worked well for 1 week. The Vector just quit on me. I am disappointed with the product not only for the obvious longevity issue, but the total lack of any serviceable reset or overload protection. My recommendation: DON'T WASTE YOUR MONEY.
