I purchased the Spigen curved crystal and had no issues applying it and have to say that it looks and feels great, is smooth and resists smudging. Everything has been positive except for I've started to notice that it seems like the screen protector (for lack of better word) dents easily. I've noticed two patches of dimples where there was nothing before. It is becoming more noticeable as well. Has anyone else seen this on the Spigen screen protectors? It is too hard to photo, but you can feel it if you run your finger over it. I am using the curved crystal with the samsung flip case.
