The ShiShuang is the first 2x2 released by the company Fangshi. Out of the box it was dusty and had these disturbing tiles. The turning was ok to say the least. It was smooth and gave some signs of crispiness. The corning cutting was decent as well. Cutting at 45 normal and 1/2 reverse. Lock-ups happen here and there; but, they are not a bug issue. What is a big issue though is the tiles (and this is a major reason why it is getting 3 stars). They are somewhat dull colors and are flush with the piece itself. It is like turning a stickerless cube (in a way). What made me mad was that there was no way to take the tiles off without damaging the puzzle. I tried putting fitted stickers on and it works; however it feels awkward due to those tiles. Overall, it is a decent puzzle; but, I would not recommend buying it.
