This pack protectors held less than a week with me. As long as the phone is not used, the film works well, otherwise you have to replace them very quickly, because at the slightest stress scratches occur. After my phone eg was in the purse next to the keychain, I could no longer recognize areas on the display. Even if the phone has been filed with the display facing downwards, there were scratches. Even after prolonged normal use of the touchscreen, frequently touched points were quick rough and worn.
Given the low price can get over this bad buy, as well as the delivery was very fast, so I am satisfied with the seller at least.
