Roving Sign, I hear you! My problems, regardless of manufacturer, are trying to get the styrofoam out of the box without shredding either, and then when replacing the car, the clear "window" plastic gets caught. Once it's bent up inside the box, you're doomed. That's when I break out the tape and tack the plastic back down. I'm normally very careful with my possessions but these modern boxes do not seem to be designed for frequent use.
Just one woman's experience.
