By the way, if you are looking for a good iPhone 6 case, do consider the iPhone 6 Case, Spigen Slim Armor Case for iPhone 6 (4.7-Inch) – Metal Slate (SGP11169). I just purchased it from Amazon, and it is working well. Looks quite good quality too. By the way, buying from Amazon is much faster than buying from the Spigen Singapore website. (see the reviews of the Spigen SG Website at Hardwarezone) Amazon delivery is always fast and reliable, even when shipping from a faraway place like the US.
