The packaging was very protective. The glas fit perfectly to my A7RIV. After cleaning and drying with the provided wipes, I stated to instal it/stick it starting by right side, and it stick like magic without any bubles. It seems it not affect the quality of the image. I didn't try the touch screen function, if it's still working, I will see later, but in any case, I not so used to use touch screen I feel better to have installed it, it was a bit slow to receive it.
Good quality and it fits with my Sony ZV1.
