Hi all, I am looking for the best quality screen protector for my new iPad mini. I have tried the Tech Armor ones which I ordered from Amazon and they are very grainy and squeak when I use my stylus with one on it. I do a lot of book and magazine reading, and use my iPad with GoodNotes for school to annotate the class PDFs, so the squeaking is unacceptable. So, any suggestions for a better quality screen protector for the uses I have? Thanks in advance.
