Note 4 clear case question?

A

AC Question

Hey guys,
I'm thinking of picking up the Ringke fusion clear case for the note 4. So i have a few question for those who have the case or used it...
What is the case made of? Is it a plastic back and TPU bumper?
Does the case scratch easily or get a yellowish tint overtime?
Does the phone get scratched when taking it in and out of the case (the metal frame or the metal bezel)?
Is there a lip over the camera lens for protection when putting it the phone on the table?
Thanks!
