terrible processing was probably used before

I got the screen for my wedding ordered, so the bride and groom in the rain to get wet. When unpacking was clear that the shield was probably used tape were top which were partially rubbed off. The screen is shaking very strong in the open state. Is remember that the size of the screen for the cheap processed plastic bar is too heavy. Since I marry Saturday and today is Tuesday, I will not send the screen back as we go directly into the honeymoon.
The screen went straight to the garbage can go now going to buy an umbrella.
Thanks for the time you gain not !!!!!!!!!!!!!
