Hi everyone, I just got my Shenshou kilominx and was disappointed by the lackluster reverse corner cutting. I quickly realized that the corners catched on the center caps and not on the center pieces per se. So I took them all out (not just the small pieces, but also the big plastic "ring" that housed it) and now it amazing. It reverses line to line almost with no effort. I guess Shengshou covered the screws for aesthetic reasons but they didn't really think this through, did they . I'm sorry if anyone had already come up with this, which I guess it's very likely as it's a very simple mod, but I searched and apparently found nothing.
