I bought one for the K5 which, when delivered was just a standard 3" screen, BUT for the reasons that the originator of this post seems to have found with the broken screen protector, I decided that fitting one of these glass screen protectors just wasn't worth the risk.
The whole reason for fitting a screen protector is to protect the screen, BUT when it breaks as they seem to do, you risk damaging the very screen you wanted to protect.
I opted for a Vikuiti™ screen protector ADQC27 for the Pentax K5, which is Crystal-clear, anti-reflective,Hard-coated' Dirt-repellent, simple to apply, residue-free removal & bubble free - most importantly - it DOESN'T break.

As you can see from the attached image, it completely covers the LCD Screen without covering up the Pentax Logo; a second protector is also provided for the top LCD.
