This triwing has not once failed me. Used it six times at least on DMG-01 gameboys (The Original Gameboy) it has not dulled or scratched or broken any of the screws inside or outside. Funny thing is I was working on the screen and when I was supposed to unscrew the screw with a #00 screwdriver, I picked up this triwing while daydreaming, and unscrewed the bit. It stripped pretty badly, the screw I mean, but the triwing looked like it suffered no abuse! That's a quality tool.
