You figure to be some golden arm can make sparks with an end wrench? I agree I got a small handful of snappies I finally relegate to a drawer but I don't think I am the only one ever used a wrench. I got a 10 inch adj snap, yes parts of it are a bit more pretty and shiny objects are attractive but never pick it because its "better" than the ATD one which really impresses me considering the vast cost difference and the fact that in thousands of cycles never found one thing the other one could do it couldn't.
Never,,, every bit as good as a human operator could tell as a Proto or Diamond, I actually like the jaw better, it opens a class wider. Will fit a one inch trailer ball.
