Shortly after unboxing my StroboStomp HD, I had a loose cable roll over and the tip banged right off the pedal. Those few moments between hearing the CLACK! and determining the screen was unharmed were enough to convince me that the Tempered Glass Screen Protector was well worth the extra few dollars. Mine arrived in the mail today, and it installed in seconds. The screen protector ships with everything you need to clean and dry the screen before application, although I would suggest you get some compressed air involved in the project. As far as installation goes, the process is similar to applying a screen protector on a mobile device, but somewhat easier due to the rigidity of this particular protector. Given the layout of the display, I opted to apply mine right-hand-side-to-left-hand-side, top-to-bottom so that any air bubbles would be forced to the bottom-left corner, where there aren't as many screen elements when you bring up the UI. I'm usually pretty terrible at applying screen protectors, but as luck would have it, I only got a couple of tiny bubbles, and they're in the black bezel surrounding the screen. Win!
One nitpick, kind of silly really, but, I would have liked the front of the screen protector to have a protective film of its own as a kind of a first line of defense against the next thing that inevitably crashes into my fancy pedal. But that's just me, I have that 'good thing I left the film ON' kind of luck.
