The Spigen Glas.tR is arguably the king of screen protectors. Before buying, I want to know how it affects the user experience. It's been well established that the spigen glas screen protectors add a small amount of bulk and don't fit with many cases. However I'd like to focus on image quality. Are there tests for changes in colour and image quality with the glas.tR and an iPhone? One thing I love about the iPhone 5 is how the LED is fused to the glass. Does the spigen glas.tR take away from this experience at all? The other day I saw BlackBerry PlayBook and the image was deep in the device. I'd hate to change the way my screen looks and feels.
