Seems a bit unstable

I've bought the shield, because I thought she was a sensible investment for my NEX-C3.
The bezel itself fits perfectly on the display. Unfortunately, I did not at the beginning, like rum open the side panels so that my page had dropped. This happened in my opinion, much zuschnell. After I got the part reattached tedious, I was able to test the shield.
In the sun the shield served its purpose. The display can be read clearly better than before. However, negative, I notice that the screen drops from time to time, when you try to rotate the display. Otherwise, this product is a useful addition - especially in the summer.
