I used the Best Skins Ever matte screen protector for about a week on my iPhone 6, before removing it a couple days ago. Here are my thoughts:
1. Loved the texture, especially for swipe gestures and texting
2. Fit was good, but maybe it could've stretched closer to the absolute edges of the screen
3. Visibility sucked! I've used matte protectors in the past, and while I knew it would reduce visibility, this was the single worst I've seen. There was a pixelated rainbow effect on the entire screen and looking at photos was terrible - it made the beautiful retina display on the iPhone 6 look like a non-retina display
Unless I can find a screen protector that perfectly fits the contours of the glass and improves the texture for swipe gestures and texting (try swipe texting with a warm hand that isn't entirely dry), I'll be going without a protector. Turns out it only costs $109 to replace the screen on the 6, so I'll take my chances.
i'd generally agree with all of this. i thought the matte screen protector from BSE was like most other matte screen protectors. maybe just a hair worse, but mostly the same. i removed mine as well and put their glossy screen protector on instead and i'm happier with that overall.
