Query: Worst quality product I have seen

I am looking for a small footprint UPS and selected the Tripp Lite because I thought it would be prefect to sit on my desk. I received the Tripp Lite BCPERS300 in a light package. The box inside was properly sealed and fit the device tightly. When I pulled the Tripp Lite out of its box, its enclosure literally split in two, and the electronic components were in full display. I never saw something like that before. The device's enclosure's two parts meet in the middle, lego like, except that they don't hold together. If you hold the device on one end, the other fell apart. If you want to see what it is inside, this is the perfect setup, you don't need any screw driver to open it! But in term of quality, this is the worst thing that I have seen in a very long time. I am not sure if this is part of their ventilating system but I don't believe that a UPS should run with its gut open. I returned the product without any problems.
