Had mine for a couple of months now (the original model from Japan, off Amazon). No scratches whatsoever on mine. Fingerprints are awful, but that's to be expected with a clear case.
One issue I do have is some crackling at the very edges inside where the back joins the sides (looks like cracked ice) from removing and reinstalling the case. So I can't call it a good choice if you feel you need to clean the inside regularly (I don't, seems to stay clean enough on its own) or if you need to swap SIM cards frequently.
Looks fabulous with my printed DecalGirl skin though, and overall it's holding up pretty well. Best of all, unlike every "frosted" soft touch case I tried or the colored Apple bumpers, there's absolutely no staining on it, so it doesn't get the filthy look the others did within days or weeks.
