I hesitated between 3 and 4 stars

As the title I hesitated to put 3 or 4 stars.
For now I have nothing to say about the quality of the product. I bought it to protect the screen of my Nikon D7100. It coincides well with the dimensions of the aps-c.
I have taken all my precautions when setting up. I thought it was good. But on the upper corner of my Nikon, collage did not fully. We see that it has not joined completely. Then eclairé screen, it does not hinder in any way. Desktop Protection does his job and I fear less for my D7100. But is it me, despite all the attention to detail that I used to install it, or is it the Lamor that do not adhere perfectly, that is the question ...
Anyway all in all I am satisfied and this is the main!
