A priori it is a good product, but I used the Glass.tr competition which certainly cost 10 more but do not have the same quality. If the package and installation are equivalent, the Holy Grail is very sensitive to fingerprints and reflections (much more than the iPhone's glass). In addition, a series of small dots crisscross the glass and visible: it's not much but they quickly capture attention.
I think it will also protect well my iPhone than competing protections, but in terms of comfort, it is unfortunately no comparison.
