The windshield did not adhere in spite exact procedure for guidance on the entire surface of the display of the Canon 6D. When trying to get it now, I have the disc finally made itself useless.
Here the detailed review:
The disc is packed in a nice plastic box consuming that puts itself back in a cardboard box. After unpacking I have kept exactly to the instructions and the camera screen thoroughly cleaned first with the damp cloth and then with a small microfiber cloth. A single then from the air on the display landed dust I have finally removed even with the "Cleaning Tape".
Now I have the protective film A from the windscreen deducted, the disc placed and pressed well centered on the display. A central, oval area of the disc stuck fairly decent on the display. Unfortunately, however, remained around this area permanently, an air gap between the glass and the display, which could be eliminated either by pressing or by brushing with the supplied squeegee. Approximately 50% of the area at the edge of the disc remained light, without liability. As long as you put pressure on the disc, the air gap disappeared at exactly the pressed-point to but when the pressure to open up again immediately.
That the disc stuck only in the middle, has initially bothered me because of the optics (center dark, the outside light). Above all, I was worried that not permanently holds the disk and eventually penetrate dust and dirt in the gap.
Well I thought the disc was also on the adhesive side of a glass surface, as I had mistakenly read out of the advertising and the product video (although that is there never really asserted). Physically would be the not uncommon one knows the adherence planer glass on glass panes.
I solved the disc carefully to clean the adhesive side with the wet wipe. I hoped to be able to improve adhesion. Unfortunately, it was so done to the disk, it was useless! The disc has on the adhesive side of a glued, rubber sheet, which establishes the actual connection to the display. On this rubberized surface of each fingerprint, every speck of dust and every fiber stuck out a cleaning cloth and can no longer be removed without further notice. Rinse with distilled water also helped only partially, because it still remained spots and particles back to the disk. A drying is also not possible, since the fibers of a cloth remain immediately adhere again to the surface.
Conclusion:
Maybe I was just unlucky with my copy or the principle works with my Canon 6D not so good, because the display is invisible possibly slight convex. Had I given myself satisfied with the partial adhesive disc, the product would have been possibly available. So I destroyed it because of lack of information, because now many clearly visible particles adhere to the rubber layer, which I do not wegbekomme.
So Do not touch the adhesive side of the windscreen (side A), either with your finger or a cleaning cloth! The rubberized surface is thus irreparably damaged in my view!
Since no surface adhesion has been achieved, I forgive only two stars. I give two stars instead of one because I can not rule out that the disk would have been anyway, albeit with visible blemishes, usable.
