Larmor Self-adhesive LCD Glass Screen Protector 3 Inch 4:3 New ggs screen note this item is 4:3

After using other GGS products that I had good luck with I decided to try this for a new camera.But this one is total junk. It actually cracked while installing.Instructions say to gently press center and it will self seal. Maybe I had a defect. I mean, it sits flat on the camera LCD so its not like you can press to an uneven surface.
