There's a cute little placard inside the box proclaiming "Amazon Refurbished". My advice: be more cautious with your advertising, or be more thorough with your work.My unit was packed very securely and delivered without damage to the box, making it very unlikely that a securely attached metal screw could have unscrewed itself while in transit. Yet, when I released the unit from all the tape and cardboard and tightly wrapped plastic, I noticed a disturbing rattling sound that turned out to be a loose screw inside the chassis -- which, by the way, is full of electronic components with exposed metal connection. Not the place you want to find a loose bit of metal.If there is a quality control department associated with "Amazon Refurbished", please, do better.
