The "bulletproof glass" has already saved me on the D7000 the display. Somewhere launched by the edge of the display and splintering with jumps all over the screen. Without the GGS Armor a new display would have been due and the costs. Based on these experiences, I have also provided my D610 with a GGS Armor. This calms! Just a note: My review refers to the wheels with the adhesive edge (settled after the break removed without residue). There is also a version that works with adhesion. Since I did not quite clear. Conclusion: 5 stars for the product and delivery.
