As negative I feel the "bad" edge adhesion, and the film sometimes quite rapidly dissolves on the edge and dust from accumulating etc. there. But could also be caused by the rounded edges! Otherwise, the film does not surround the home button, making these small edges are very sensitive under the Home button and dissolve very easily! Another point, the safe with so far no protective film is however available for the iPhone 6 that approximately 5mm around is not a protector on the display. Due to the rounded edges. But for me not only an optical defect but not the purpose of a protective film. Once you have ordinary protectors on 4 / 4S / 5 / 5S hardly noticed, you see it here right away! I will remove the screen protector again and use it without, but with decent shell. The money for protectors (though not much) you can, at least in the 6 / 6P, save!
