This is correct, I've opened mine and it is unresponsive. They do this by cleaning/not lubing/using thinner lube on the bearing. The setup, otherwise, is exactly the same as the stock package. Still the same size bearing and same brake pads. Buyers can improve unresponsive performance by installing a full size-C bearing(these come with half-C-size bearings), and/or switching the pads for silicone pads(can be bought or made.)(also, YoYoJam sells the bearings and pads as a kit intended for the YYJ Classic yoyo) In fact, it would have been cool if they had done this beforehand, but it's still a decent price, so I don't really mind changing these parts myself.
