I bought this one from Amazon and it's been really good so far.
It was like $12 when I initially bought it, so I figured I didn't have much to lose with Amazon's return policy.
This is my third edged display (S6e, S7e) and I've never used a tempered glass protector, so I wasn't quite sure what to expect.
I've had no loss in touch or S Pen sensitivity, adheres well and no screen distortion that I can see.
As for case friendly, I'm using the Incipio Dual Pro (black) and I was curious if it were going to fit well because the case protrudes about a milimeter around the entire phone.
Fit without any issues.
$53!? I bought this one for under $12 and its been fantastic the past week, and it's case friendly.
