My silver CC got really scratched, it scratches really easily, just by looking at it. And it's very noticeable on the silver pandora. I would higly, highly recommend to also buy the carrying case if you don't have it already...
I ordered a black case replacement to get a fresh new look without scratches, plus I always wanted a black one together but it wasn't available at the point when I first bought my pandora. Bought that together with a carry case and have been super happy with it (and also SUPER careful, always lifting it straight up, slowly, never lightly dragging it towards me making contact with the table, never putting anything on top of it etc)
No hinge problems or anything, it's solid without cracks. Did have some issues assembling it though as two of the holes for the screws needed to be glued in as there was damage to the case parts. And needed to file down a little bit for the shoulder buttons.
And yes, the battery cover is much better for the silver case. Works if you're careful though, mine's still intact but doesn't "click" in 100%, more like 98%.
