I just received and installed the Zagg Invisible Shield Glass Curve. Yes, it is expensive but it is different and I think it is really good!
1) The installation is idi0t-proof. They have a new system that makes applying this protector really easy and perfectly placed.
2) I have not found any screen sensitivity issues whatsoever (so far).
3) I have a Samsung Alcantara case and there does not seem to be any issues with the case compatibility.
I will update this post if I find any issues, but so far this screen protector looks and feels great. (I have used Zagg Glass before on previous devices and some worked fine and some had screen sensitivity issues.) This one for the Note8 is very different and I am hopeful that it performs as well as my first reaction!!
