I also have this exact screen protector, it's really nice.
Only cons are dust getting under the gap, and as you say the white edges.
Also the new version of the Benks screen protector doesn't have white edges: http://www.benks.us/screen-protecto...hone-6-full-front-glass-screen-protector.html![]()
The new black version, without the white outline, will be available around 4/10 on Benksus. The white has no outline.
I'm using the case friendly Benks 0.15 thin glass and it's great quality. Extremely smooth, crystal clear and perfect adhesion.
The white edge to edge I tested was also the same quality. It just didn't work with my favorite case or I would still be using it.
