Just recieved my TangPo. When I disassembled it to have a look at the inner workings, I discovered that most of the pieces are identical to that of the YJ YuPo. I'm not just saying "Oh they used a similar ol' mechanism to almost all speedcubes nowadays", I'm saying they literally reusued the exact same core, center pieces and inner "edge" pieces used in the YuPo. The only difference was in the "corners" (which, granted, are the only actual cubies in a 2x2), but even then, the difference is highly minimal. Asides from changing the piece fitting from the old "three-piece" design to the "capped" one, there's practically nothing new to affect the function, asides from slightly thickening the "base" part of the stalk (You know, the big bit closest to the core, dunno the correct terminology). I'll post comparison pics later.
What was even the point?
