Amazon.com.au:Customer reviews: TERSELY Screen Protector for GoPro Hero 7 (2018) Black /6/5, (3 Pack) 9H Hardness Tempered Glass Screen Protector Front Camera + Back Glass Lens Protector Film for Go Pro Hero7 Black Hero6 Hero5
Not much money for peace of mind when it comes to an expensive camera you'll be throwing at stuff. No colour or image quality effects, very easy to forget you have them on and then buy lens caps and such anyway despite them being redundant. No loss of sensitivity on the touch screen however I notice slightly diminished responses in the skeleton suit, possibly related to pressure on the screen from the frame? Either way, very happy with the purchase.
