While a heavy fall or item dropped on your screen will likely damage it regardless of any protector, for the normal mishaps of the day this screen works great and is a small cost for the value it provides.

As careful as you might be an accidental drop of the Ipad or something falling on the screen such as the coffee cup you are drinking from as you browse the web, can damage or totally destroy your screen

I had the same brand on my phone which shattered after a nasty drop, but the actual phone screen still looked new after I removed the protector

Glass Screen Protector protected my IPad Mini 4 in an accidental drop from a low table--though the tempered screen cracked.
