Ball Shifter Vs. Dog Shifter?

No wear on either (for lack of a better term) the steel ball containment shell, or the gears. This thread has some good videos of what not to do with respect to the VexPro ones. While ours was not as obviously incorrectly assembled as is shown in those videos I suspect the travel was adjusted slightly incorrectly resulting in the accelerated wear pictured.
