Problematic delivery, quality okay

Had I ordered the display, because my iPhone had jumped 4 display. The first delivery that I received, was empty. After installation of the display from the second delivery, I had to find that the touch screen worked, but the screen remained black. After further expansion, return and reinstallation of the display from the third delivery now everything works.
The quality of the display is fine. Fit well with respect to the camera hole is impeccable, the speaker cover, I could take over from the old display. The brightness control works also. Unfortunately, the display at oblique is not draufschauen so color fidelity as the original, in one direction, it is light blue and the other red-rather fusty. In addition, to show in transparent parts of the image light transverse lines. Those who accept this slight shortcomings, and the rather elaborate installation (I have the ifixit.com guide uses) is not afraid, for the display is certainly the most cost-effective alternative to a repair at Apple Authorized Service. Without the problematic delivery there would have been even more stars.
