I had problem with the 2 screen protectors, any of them paste well on the screen. Very disappointing because I also bought the complete screen protection and I hope not happening the same thing...

Ex Output:
negative


Ex Input:
Bought this after reading good reviews. But it’s not water proof at all. If my son has even a little accident in bed, it goes straight to mattress. I don’t see a point in having this. So I have to purchase another one.

Ex Output:
negative


Ex Input:
I bought this in anticipation of eventually getting an iPhone 11, and it looks really good! The design is sleek and hip, and I like the raised edges a lot. The transparent back feels sturdy to fit a card holder on, and it also doesn't interfere with my wireless charger at all. Overall, pretty solid product that I expect will last a long time.

Ex Output:

positive
