I have been using the Eurpmask tempered glass protector since the end of September and have no issues with it. It comes with an alignment tool that makes it easier to install. It also works with all 5 or 6 of the cases I have, 2 Spigens, 2 Encased a Youmaker and I think there's another one that I forgot about.
Anyway I'm on my 2nd protector, because my phone was knocked off a table, outside, by a gust of wind and landed face down on Belgium block pavers. The only thing that cracked was this protector, I peeled it off and ordered another. While waiting for it I realized that I wish I could go bare, but won't risk it. Bare is beautiful, but this protects my screen and I don't notice any loss of sensitivity.
