Query: Underwriters Laboratory?

Seriously, who thought that this was hassle-free? It took me two days and a morning to configure this thing. Not that it isn't fun to use, just that if I were to look at it's smooth lines and no gimmicks chassis, I would have thought you would have made this a better product?! You get what you pay for? It could have been much cheaper with as much tweaking I had to do.
