The sticky tabs meant to hold the protector in place flew off, the protector flipped into the air, and I almost sprained my wrist trying to catch it. It was hard to apply centrally as it's a little too small for the screen, and it ended up not adhering following its amateur gymnastics.
I bought a new one in the hope I could get it right this time, and application was a little easier, until I held my phone up and noticed several specks of fluff under the protector that will slowly drive me round the bend until I can afford to try again (third time lucky?)
While I thought my second protector had at least adhered well, it started to separate from the screen after a couple of months. All in all, a disappointing and expensive experience.
