The Sansa e200 Silicon Case does it's job. It's awesome compared to similar products - keeps the sansa from sliding around in the car, keeps scratches away etc., easy to put on and off, pretty much indestructible. Only disadvantage about it is the look - it takes the originally noble and shiny look from the sansa. some might also find that it is a little bit harder to reach the buttons - i didn't have this experience myself.
