Query: poorly implemented

Plastic refracts the light over the screen to make it hard to read when going out doors, or glancing down at it in my car.Very easy to scratch your ipod since it's a slide in case.At least for me, the bottom cap that is supposed to secure the ipod in place never really fit right when the ipod was in, only when I took the ipod out did it fit correctly.It traps dust underneath the case, especially surrounding the scroll wheel, which requires consistent cleaning.Area around the top also allowed dust into the case, especially the back, which contributed to the scratching on my ipod.Their plastic sheath they provide does not do an effective job of protecting the ipod from scratching, especially since it gets caught on the lip of the case.Decent design, but very poor implentation.
