It was spilled all over inside the envelop when it was delivered, no safety seal. When I tried to request a refund, it said not eligible for refund, contacted seller and sent picture, no further response. Posted review twice but nothing showed up, what is going on?!

negative

Ex Input:
This came with all the materials to apply the screen and it was easy to apply. However, it lasted only a couple days, then a giant crack. I replaced it with the second one. The same thing a few days later. The phone had NOT been dropped. My screen has been fine for the year and a half that I've had it, minus one scratch. I don't understand why these protectors won't last.

Ex Output:

negative
