Motorola Droid :: Imperfection - Loose Battery Cover

First droid had an imperfection on the glass screen that caused a black spot (prolly 3-4 pixels big) on a white background in which I could not fix because it was part of the glass. Second droid had dust infiltrating on the sides leading to a distraction when viewing the screen. Now, my third droid has such a loose battery cover that it comes off in my pocket a lot. Am I too picky or do I just have bad luck? Really don't want to go to the verizon store again for a loose battery cover but I think that is a legitmate problem, and btw I have tried a different battery cover and that isn't the problem, it must be what the cover hooks onto inside the phone that is causing it to be loose.
