I ended up returning the Stone colour one and went with Navy Blue, one day with jeans on and the blue was rubbing against the case luckily was able to get the mark off. Amazon UK had a sale on as the stone case was £64.99 got the blue one for £51.99 but overall good case apart from the issue with the lighter colour.Returning mine too, it feels horrible in the hand compared to the Ultra Hybrid Zero One..you'd think they'd be the same wouldn't you.
