The screen protector that is built on the case doesn't adhear to the screen itself, so since I work in a dusty environment, there was alot of dust that

Maybe it is OK for drops and whatnot, but this will have dust under the screen protector, in the buttons, and everywhere within 5 minutes, even if not exposed to dusty environments

But as others have stated, somehow dust gets under the plastic cover within days of use, and my environment isn't dusty.

I also work in a dirt and dust filled environment and the case does a fairly good job at keeping most of it off of my phone

This is for my company phone which is a rough environment.

I work in a dusty environment, and I had to take off the entire case several times a day to clean it out because I couldn't use my phone with sand stuck underneath

Its a drop proof case, but when it comes to working in a dusty environment the case traps the dust and dirt between the screen protector and screen, making using the keyboard imposible and scratching the screen.
