I haven’t found a difference between a $2 screen protector and a $50 screen protector. It’s the same on phones and tablets. The one on my iPad now came from the Verizon store and probably cost me $50. It’s highly reflective. The one on my phone came from Amazon and it was about $6 if I remember right. It’s just as reflective.
I’m willing to deal with a little bit of screen glare because I know it will save the screen from damage.
