They probably had it in the sun for a year....the visor wouldn't come off no matter what until the glass broke....it became garbage as soon as it was bought...

First time I placed a protective glass on any device. I found the installation a bit difficult, resulting in leaving marks on the screen (which may be due to my inexperience, even though I installed it on a mobile and it seemed like an easier process afterwards). Other than that, it seems quite durable and it has been protecting it well up until today.
