The QiYi QiHeng S2 Megaminx - Stickerless is QiYi's 2024 overhaul of the long running QiHeng dodecahedron. It comes in at about 126g with moulded colour across all twelve faces. The construction runs stable and pop resistant, and screws beneath the centre pieces let you retension the puzzle to your liking. Buyers who want layer alignment assistance can step up to the QiHeng S2 Magnetic, which adds factory fitted magnets to the same body.
